Computationally efficient simulation of unsteady aerodynamics using POD on the fly

Modern industrial aircraft design requires a large amount of sufficiently accurate aerodynamic and aeroelastic simulations. Current computational fluid dynamics (CFD) solvers with aeroelastic capabilities, such as the NASA URANS unstructured solver FUN3D, require very large computational resources. Since a very large amount of simulation is necessary, the CFD cost is just unaffordable in an industrial production environment and must be significantly reduced. Thus, a more inexpensive, yet sufficiently precise solver is strongly needed. An opportunity to approach this goal could follow some recent results (Terragni and Vega 2014 SIAM J. Appl. Dyn. Syst. 13 330–65; Rapun et al 2015 Int. J. Numer. Meth. Eng. 104 844–68) on an adaptive reduced order model that combines ‘on the fly’ a standard numerical solver (to compute some representative snapshots), proper orthogonal decomposition (POD) (to extract modes from the snapshots), Galerkin projection (onto the set of POD modes), and several additional ingredients such as projecting the equations using a limited amount of points and fairly generic mode libraries. When applied to the complex Ginzburg–Landau equation, the method produces acceleration factors (comparing with standard numerical solvers) of the order of 20 and 300 in one and two space dimensions, respectively. Unfortunately, the extension of the method to unsteady, compressible flows around deformable geometries requires new approaches to deal with deformable meshes, high-Reynolds numbers, and compressibility. A first step in this direction is presented considering the unsteady compressible, two-dimensional flow around an oscillating airfoil using a CFD solver in a rigidly moving mesh. POD on the Fly gives results whose accuracy is comparable to that of the CFD solver used to compute the snapshots.

Household Appliance Product Appearance Design with Feedback of User Experience

Household appliance product design is a big trend in current industrial design circle. Reverse engineering is one of the most common CAID means in modern industrial design. In order to support reusing product appearance design knowledge, this paper proposes the model used for resolving innovative product appearance case. According to the three stages of aesthetics impression, semantic judgment and symbol contact experienced by users to cognize product, this paper divides the product into three kinds of appearance innovative types of formal aesthetics, usage mode and cultural fashion. By utilizing taxonomy principle and appearance design innovative process, this paper sets up three kinds of appearance innovative types corresponding to design knowledge frame model used for extracting and reusing appearance innovative design knowledge. Such model is applied to setting up product innovative case library, helping designer search and apply previous successful cases and realizing user-centered product development. Through the use of such database by designer, this paper shows its effectiveness.

Numerical experimental analysis of hybrid double lap aluminum-CFRP joints

Due to their reliability and ease of assembly, both the adhesively bonded and the mechanical joints are commonly used in different fields of modern industrial design and manufacturing, to joint composite materials or composites with metals.As it is well known, adhesively bonded joints are characterized by high stiffness and good fatigue life, although delamination phenomena localized near the free edges may limit their use, especially for applications where corrosive environments and/or moisture can lead to premature failure of the bonding. In these cases, a possible alternative is given by the well-known mechanical joints. On the contrary, these last joints (bolted, riveted) require a preliminary drilling of the elements to be joined, that may cause localized material damage and stress concentration, especially for anisotropic laminates characterized by high stress concentration factors and easy drilling damaging, with significant decrease of the load-carrying capacity of the joined elements. In order to exploit the advantages of the bonded joints and those of the mechanical joints, both industrial manufacturing and research activity have been focused recently on the so called hybrid joints, obtained by the superposition of a mechanical joint to a simple adhesively bonded joint.In order to give a contribution to the knowledge of the mechanical behavior of hybrid bonded/riveted joints, in the present work a numerical–experimental study of bonded/riveted double-lap joints between aluminum and carbon fiber reinforced polymer (CFRP) laminates, has been carried out. It has permitted to highlight both the static and the fatigue performance of such joints obtained by using aluminum and steel rivets, as well as to known the particular damage mechanisms related also to the premature localized delamination of the CFRP laminate due to the riveting process.

The Modern Tableware Design Based on Fengxiang Clay Sculpture Art Research

The development of modern industrial design has a great influence on the product design, not only on the function and structure of products, but also on the combination between these elements and culture. As one famous folk craft of Shaanxi Guanzhong Xifu, Fengxiang sculpture consists of lot totems, pattern, shape, color and craft elements which could be used in design. Tableware design combined with traditional culture can reflect the functions; at the same time improve the artistic quality of products and rich the interest. Products are endowed with the traditional culture elements, in this way, the product is not only a product, but the new soil of the traditional culture.

Thinking about the Theory Construction of Chinese Industrial Design

Concerning on the current vague definition of industrial design in China, this paper indicates that industrial design and engine design are compound concept. In the first place, it introduces the definition and theory of industrial design. Then, by analyzing design development and industry development relationship, it regards modern industrial design as a heritage and a production from the development of traditional handcraft design. Finally, it proposes that in order to regulate a modern design theory with Chinese characteristics. We must learn the advanced industrial design theory from the west. At the same time, we must fully excavate the essence of traditional Chinese handicraft culture. Also we should integrate Chinese traditional handicraft design theory into the west modern industrial design theory.

Does (the) Form Follow Function?

‘‘Form follows function’’ is a principle associated with modern architecture and industrial design in the 20th century, which states that the shape of a building or object should be predicated on its intended purpose. The origin of the phrase is traced back to American sculptor Horatio Greenough, but it was American architectural giant Louis Henri Sullivan who adopted it and made it famous. Sullivan originally said, ‘‘Form ever follows function,’’ but the simpler ‘‘form follows function’’ is the phrase usually remembered. This term became Sullivan s aesthetic credo and was for him the ‘‘rule that shall permit of no exception.’’ In the era of quality-of-life (QOL) analysis, and specifically in reference to the paper by Newman and colleagues from Memorial Sloan-Kettering Cancer Center (MSKCC) in this issue of the journal, the more compelling question becomes, ‘‘Does the survey form follow function?’’ The authors have utilized a specific form developed by the European Organization for the Research and Treatment of Cancer (EORTC) and have applied it to 123 of their own patients who have undergone sphincter-preserving surgery for stage I–III rectal cancer. They have utilized two specific forms developed by the EORTC that measure global QOL as well as social and physical function (EORTC-C30) and a specific instrument that measures gastrointestinal symptoms and defecation function (EORTCCR38). In their Methods section, the authors have alluded to utilizing a ‘‘modified Dillman method’’ but have not defined this for us. Obviously the methodology of conducting surveys may be one of the more important aspects of the outcome of their analysis. The concept of the Total Design Method was developed by Don Dillman and is applied to survey methodology. It is based on the principle of convincing the study cohort that a problem exists that is of importance to a group with which they are identified. More importantly, the subjects are encouraged to participate because their help is needed in finding an important solution to a problem. Dillman reports that a researcher should be portrayed as a reasonable person who, in light of the complexity of a problem, is making a reasonable request for help, and that this help by the subject will contribute to the solution of an important problem. The reward for the respondents is derived from the overall feeling that they have done something important to help solve a problem faced by them, their friends, or members of a group, including their community, state, or nation, whose activities are important to them. Newman et al. report that the survey instruments were distributed to patients at the time of their clinic visit to MSKCC or through the mail by using a modified Dillman method. We are left to conjure as to the definition of a ‘‘modified Dillman’’ method, but we can only assume that the tenets outlined for survey completion by Don Dillman in his original treatise were followed. It is clear that the approach of researchers to respondents in a survey-related research effort are important to the outcome. Surgical outcomes can be assessed in a number of ways, including complication rates, overall mortality, length of hospital stay, or economic consequences.

Formulation of mixed elements for the 2D‐BEM

Accuracy and time consumption in numerical computations are often in contradiction to each other. In modern industrial design processes flux field computation becomes more and more important. Thus, it is desirable to minimize any methodical error for better performance. This paper discusses a flaw of frequently used standard elements in boundary‐element‐method and shows a way to avoid it.

John Cotton Dana and the Politics of Exhibiting Industrial Art in the US, 1909-1929

Between 1909 and 1929, John Cotton Dana directed New Jersey's Newark Museum and pioneered the museum exhibition of mass-produced goods, initiating a trend among American art museums, including the Metropolitan Museum of Art and the Museum of Modern Art in New York. Through his work, Dana hoped to reform the museum community, society and industry. He saw his museum's activities as a progressive response to the problems of increased industrialization, an expanding consumer culture and the country's search for a national aesthetic based on the machine. This paper examines Dana's influence by investigating his correspondence, publications and exhibitions, including the first display in America of modern industrial design, the 1912 exhibit of the work of the Deutscher Werkbund.

Individual prefabricated titanium implants in reconstructive craniofacial surgery: clinical and technical aspects of the first 22 cases.

The reconstruction of craniofacial bone defects by intraoperative modeling of implants restricts the choice of material and its biocompatibility and also reduces the predictability of the aesthetic result. These shortcomings go hand in hand with a prolonged surgical procedure time and increased stress on the patient. In contrast, modern industrial computer-aided design and computer-aided manufacturing systems allow the prefabrication of titanium implants, i.e., individual computer-based three-dimensional models of the bone defect are generated after acquisition, transfer, and evaluation of helical computed tomographic data. Based on these data, the individual shape of the implant is designed using freeform-surfaces geometries and is fabricated by a numerically controlled milling machine in a direct fashion. The conical margins of this implant are designed with a precision of 0.25 mm to the borders of the defect, and the surface contours are generated harmonically to the nonaffected neighboring contours with a constant thickness of 1.5 mm. Individual constructions for fixation with the dimensions of microplates are integrated in this process if screw holes cannot be drilled in thin overlapping implant margins. The reconstruction of 22 posttraumatic, postoperative, or primary cranial and craniofacial defects measuring up to 18 cm was performed using this new method. Wound healing was uneventful in all but one case, although some of the patients had been operated on several times before. The result was always predictable and constant using this highly precise technique, and duration of surgery was reduced dramatically.

L'Art Dans la Production le débat sur Le productivisme en Russie soviétique pendant les années vingt

Comment l'imaginaire socialiste se situe-t-il dans le rapport entre l'art et la révolution après octobre 1917 ? D'abord il semble se glisser dans des espaces minuscules, entre les interstices les plus cachés, que le caractère scientifique du matérialisme historique avait laissés libres, à la recherche du droit à la création d'une utopie qui se dégagerait de la sphère scientifique. Ensuite il explose en une intense activité onirique, grâce à laquelle il essaie de concevoir une nouvelle société. Négligeant la leçon scientifique du matérialisme historique (qui concerne l'analyse de la société capitaliste) il privilégie la leçon utopique (qui envisage l'édification de la société socialiste), car celle-ci accorde plus d'espace à son activité fantastique.

Present at the Beginning

This juxtaposition of contrary opinions probably reflects the most truthful estimation of that postwar time. Speaking today about the Architectural-Artistic Bureau (AAB) within the Ministry of Transport Machine Building in the Soviet Union, its former associates do not even notice how easily they have reconciled these two concepts: hard and easy. It was a time of untrodden and therefore difficult roads to industrial design, of active and therefore joyful labor of enthusiasts. AAB set up the methodological basis for modern industrial design and offered an example for organizing designers' work. And its activity provided the impetus for a new stage in the development of Soviet industrial design. Researchers are still faced with the task of filling in the gaps in the study of Soviet postwar experience in industrial design, especially of the practical scientific experience of the AAB. This article will only paraphrase the recollections of a few AAB specialists who began their work there 40 years ago.
