Design and Development of Food Waste to Biogas Converter System

The valorisation of food waste via anaerobic digestion has shown to be a promising option for tackling waste accumulation and achieve energy security. In this study, a lab scale and a pilot scale anaerobic digester, with food waste as the feedstock and palm oil mill effluent (POME) as the microbial inoculant, were evaluated for their biogas production. For the lab scale study, the effect of different food waste to POME ratio, ranging from 1:1, 1:2 and 2:1, on the biogas production were investigated for a period of 7 d. From the experimental work, the ratio of food waste to POME at 2:1 gave the highest biogas yield of 0.14 L. For the pilot scale study, a digester was designed based on a daily electricity demand of 9.5 kW of an eco-park. With the use of the Pro Engineer Software, it is estimated that a digester with a volume of 4.27 m3, handling capacity of 200 L of food waste daily, and a hydraulic retention time of 15 d, can generate sufficient biogas to meet the electricity demand for the eco-park.

The production process is the core of an industry that certainly relies on a variety of equipment to help the process run. Oyster mushroom baglog industry is one of the agricultural industries that needs to be developed in its production equipment because of its good market prospects and high economic potential with a clear market segment. But there is a problem that often faced by the baglog farmers, the problem is the sterilization process from baglog itself is not good, so the quality of the oyster mushroom will decrease or worse is the crop failure. Therefore an appropriate boiler is needed that it can increase the yield and quality of a baglog oyster mushroom industry. Boilers that are designed will follow the existing standards, which are in accordance with the ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code (BPVC) standards and coupled with simulations in the form of adding loads to the boiler model using Pro Engineer Wildfire 4.0 software.

Study on Mechanical Properties of Mono Composite Steel Plate Cart Spring Using Pro Engineer and ANSYS R16.0

In global manufacturing system, reduction of weight for automobile components is the main concern in automotive manufacturing industries. This research work focuses to improve the high strength ratio by reducing the weight of steel plate composite cart spring. The objective is to investigate the total load carrying capacity, stiffness and weight savings of composite cart spring and compare with that of steel cart spring at specified loading and over loading conditions. The examination was done for the cart spring made up of steel and composite materials of epoxy resin, e-glass fiber and nano particles. The specimens were fabricated by laminated composite with two dissimilar wagering progressions of resin with clay and nanoparticles. The constant thickness and width for cross section was maintained on the moulding techniques. The proposed design of multi level composite cart spring was modeled through PTC developed software of Pro Engineer and imported in simulation and 3-D design software of ANSYS R16.0. The existing measurements of a multi level cart spring was considered for modeling and investigation of a proposed laminated composite cart spring under same loading conditions. From the results it was found that, about 80% of the weight was reduced in the proposed laminated composite cart spring by replacing steel plates with composite materials.

The Effect of Angulated Radius Fractures in Forearm Rotation: A Computer Based Model

Background: Forearm fractures amongst children are quite a common presentation. The accuracy of correct alignment in forearm bones is important as it determines the degree of forearm rotation (pronation-supination). However in children due to the potential for continuous growth, a degree of angulation is acceptable. The aim of this study was to determine the effect of angulation of forearm fracture on forearm rotation using computer stimulation. Methods: Using a 3D computer modelling software (Wildfire Pro Engineer 4.0, Creo by PTC, Needham, MA), an accurate to scale model of the radius and ulna was replicated from a 7 year old forearm. A realistic representation of pronation/supination of the forearm was applied and a fracture at the junction of proximal one third and distal two third was created. A rotational simulation was created and ended when maximum pronation and supination was reached. Maximum pronation and supination was reached when either no more rotation could occur due to a misalignment of the radius and ulna or there was a collision of the bones. The simulation was repeated in increments of angulation of 2° up to 26°. The angulations that resulted in a combined range of motion (50° pronation and 80° supination) less than 130° were recorded as unacceptable and the others were as acceptable. Findings: The study showed that radius angulation fracture of >16° in the proximal third of the radius would result in an unacceptable reduction of pronation-supination to less than 130°. Conclusion: Patients with more >16° of radius angulation in a distal third shaft fracture of the radius may result in clinical reduction in forearm rotation.

Analysis of ‘free energy’ perpetual motion machine system based on permanent magnets

Claims of “Free Energy” generation using Perpetual Motion Machines (PMM) are usually discounted by the scientific community since PMMs are considered impossible, as a direct corollary of the Law of Conservation of Energy. However for the scientifically inquisitive mind, the urge to distill reasons which make some systems appear as PMMs, remains a factor. Recently a system on permanent magnets has been observed by the author, whose designer claimed that his system can provide ‘free energy’. i.e., the output of the system is greater than the input. This system comprises of eight magnets arranged at equal distances at the rim of a circular disk and a ring magnet at the centre of the disk as shown in Fig. 1. The first magnet at the rim of the circular disk has its north aligned with axis of rotation and facing towards it. The next magnet placed after 1/8th of the circumference is rotated by an angle of 450 around z-axis such that after traveling half circumference the magnet rotates through 1800 as shown in Fig 2. The input is ring magnet which has an inner radius of 31.75 mm and an outer radius of 50.8 mm as shown in Fig. 3. The ring magnet is positioned at an angle between 300400, from the horizontal upper surface of the disk. The lower face of the ring magnet is North Pole and the upper face acts as South Pole or vice versa. In either case the face of the bar magnet facing the ring magnet is such that there is a repulsive force between the two. As the disk rotates initially, the ring magnet is positioned manually by rotating it around it’s z-axis at an angle of 300-400 to an axis parallel to the upper surface of the disk such that at an instant there exists a repulsive force between a pair of bar magnets (separated by 1/2th of the circumference) and the ring magnet. The system has been analyzed using theoretical calculations and simulation with PRO ENGINEER Wildfire 5.0 which shows that it is not a free energy system.

Methods to Increase the Rigidity of the C-Frame of a Press

Reducing exploitation energy consumption for any technical system is an effective way, which is in complete accordance with the concept of sustainable development [1]. The presses, particularly the mechanical ones, are machine tools with a long-term exploitation [2]. At these ones, the operating energy consumption, significant in value, decreases only if the rigidity of the structure of resistance increases, including that of the frame. Several analytical models, developed and studied by the authors, confirmed the hypothesis that a solution to increase the rigidity of a mechanical press with open frame is obtained by shortening it. Moreover, it occurs also a slight decrease in material consumption integrated into the frame, which is a favourable effect. There have been developed more new constructive solutions [3, 4], characterized by minimal changes to the reference design solution, that of the press frame PAI 25. The new suggested constructive solutions are obtained as 3D models, accomplished in Pro Engineer Wildfire 4, and the finite element analysis was made in Catia V5 R16. The present paper shows results on increasing stiffness and reducing stress state for a few constructive solutions of shortened C-frame, having reduced distance between the working surface of the table and the spindle bore axis.

Test and Analysis of the Mass Properties for the PRANDTL-D Aircraft

The main objective of the "PRANDTL-D" project is to obtain the stability and control derivative yawing moment due to aileron deflection, Cnδa. The sign of Cnδa determines whether the "PRANDTL-D" aircraft experienced proverse or adverse yaw during flight. Proverse yaw, the desirable outcome, occurs when the aircraft yaws in the same direction as the turn due to a novel wing twist and bell-shaped lift distribution. Accurate moments of inertia are essential in order to create a dynamic model of the aircraft and compute the stability and control derivatives, including Cnδa. The robustness of the aircraft simulation also depends on the uncertainty of the mass properties. To obtain the moments of inertia, the aircraft will be hung from two filars and rotated in a bifilar pendulum test. A wireless inertial measurement unit will be used to capture the rotation rate data during testing. This data will be used in a bifilar pendulum simulation to analyze the data and obtain the experimental values. For the tests, our team used Pro Engineer to predict the moments of inertia, designed the test structure and specific testing procedures, and created a Simulink model of the bifilar pendulum test.Â

Development of 3D Boiler Header Template using Webots

Offline boiler header inspection is a tedious process if done manually since the opening is very small to insert big instruments and tools while the length can range up to 20 m. The geometry can also be complex since boiler tubes are connected to these headers from different directions. Designing of robots to assist in offline boiler header inspections can be made easier if a simulator is available for deciding the parameters of the robot. This paper describes the development of a 3D boiler header pipe environment template for boiler header inspection robot (BHIR) using Webots. The purpose is to use it as a simulator for the development of BHIR prototypes. Firstly, 3D boiler header pipe environment is constructed by using Pro Engineer (Pro\\E). Next, Virtual Reality Modeling Language or VRML97 is used to convert file from Pro\\E world file to Webots world file. Finally, simulations are carried out to verify the effectiveness of the developed 3D boiler header environment template. Results show the advantages of having the simulator for modeling and designing of BHIR prototypes.

Simulation and Calculation to Segregation of High Nitrogen Steels Solidification Process Based on PROCAST Software

Segregation and liberation occur easily in high nitrogen stainless steels, which can result in the formation of pores and the discarding of the steels. So it is very important to investigate the segregation and liberation theory during the solidification process of high nitrogen stainless steels. In the manuscript, the pouring and solidification progress of high nitrogen steels ingots were simulated through Pro Engineer and PROCAST software. The dynamic variation of temperature field and pressure field were obtained. With the results of PROCAST, the macrosegregation of 20kg weight ingot and 1.7 tons weight ingot were predicted using mathematical model of zone segregation. The predicted results show that 20kg weight ingot has no obvious macrosegregation and 1.7 tons weight ingot has obvious macrosegregation, which is consistent with measuring results. It shows that the accuracy of simulation and calculation to segregation of high nitrogen steels solidification process based on PROCAST software is high.
