pulse tube
Figure 1.8 is a schema for the surface heat pumping effect. The mechanism can be visualized as by examining the physical behavior of one of the gas elements near the tube wall, as indicated in the figure. Suppose that at the beginning of the cycle the temperature of the gas element is in equilibrium with that of the adjacent tube wall. As a result of pressurizing the tube by supplying gas from the left end, the gas element..................[:=> Show Contents <=:]

ternally imposed boundary conditions are a cyclically moving piston wall at one end of the tube and constant temperature or heat flux boundaries at the external walls of the hot end and cold end heat exchangers. The experimental method to evaluate the optimum parameters of OPTR is difficult. On the other hand, developing a computer code for CFD analysis is equally complex. The objectives of the present investigation are to ascertain the suitability of CFD based commercial package, Fluent and also to examine the performance for the effect of compressor frequency on the orifice type pulse tube r..................[:=> Show Contents <=:]

oacoustic refrigeration. We ordinarily think of a sound wave in a gas as consisting of coupled pressure and displacement oscillations. However temperature oscillations always accompany the pressure changes. The combination of all these oscillations, and their interaction with solid boundaries produces a rich variety of Thermoacoustic effects. Although these effects as they occur in everyday life are too small to be noticed, one can harness extremely loud sound waves in acoustically sealed chambers to produce powerful heat engines, heat pumps and refrigerators. Whereas typical engines and refri..................[:=> Show Contents <=:]
