Experimental investigations on control of flow instability in single-phase natural circulation loop

Abstract Natural circulation systems offer simplicity, enhanced safety and reliability and thus are advantageous over their forced circulation counterpart. However, natural circulation is susceptible to flow instabilities. These instabilities are undesirable for various reasons. Literature suggests the use of orifices at the inlet to suppress instability. However, orificing introduces pressure drop which limits the flow rate and hence the heat carrying capacity of the fluid. In the present study, investigations have been carried out with different mechanical gadgets to control the natural circulation flow instabilities. Extensive experiments have been carried out in a single-phase rectangular natural circulation loop to study the effect of these mechanical gadgets on instability. The paper brings out the results of experimental investigations carried out on the role of mechanical gadgets in controlling instability.

The magic of machines in the house

In the 1850s, a French magician and inventor named Jean Eugene Robert-Houdin filled his home with electrical and mechanical gadgets including a system of centrally-controlled alarm clocks to wake servants, an automatic horse-feeder and a complex system of bells to detect visitors. We examine how this early intrusion of machinery into the domestic realm drew on the craft of conjuring performance and apparatus design. Through an analysis of Robert-Houdin's house, we show how the techniques of magic, specifically of simulation and dissimulation, provide a ready-made language in which to consider the accommodation of machines within architectural design. This analysis is then reflected forward to a discussion of two later cases of overtly mechanised houses within the established canon of modern architecture: Le Corbusier's Appartement Charles de Beistegui completed in 1931, and Alison and Peter Smithson's House of the Future or ‘appliance house’ displayed in 1956. Through the language of magic, these cases are discussed in terms of alternative readings of Le Corbusier's modernist mantra of the house as a machine for living.

BILATERAL PARALYSIS OF ABDUCTOR MUSCLES OF THE LARYNX

The loss of function of the abductor muscles of the larynx is a most serious and crippling condition. The fact that an adequate intake of air could be established by means of a tracheotomy tube was established many years ago. This procedure eliminated the necessity of working for each breath of air. It allowed the patient considerable latitude in regard to normal exercise but did not permit him to resume a wholly normal existence. The introduction of the valved tracheotomy tube was a step forward in that the defect could be disguised in a number of ways, but it did not relieve the patient of the worry, care and annoyance of a mechanical gadget. A certain number of patients with bilateral posticus paralysis have existed without the advantage of an adequate intake of air, which could have been obtained by means of a tracheotomy tube.
