A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. To accomplish this the hot fluid is brought into contact with the heat storage medium, then the fluid is displaced with the cold fluid, which absorbs the heat. It is stated in gFor Better Thermal Analysis and Calorimetryh, 3rd Edition, published in by ICTAC (International Confederation for Thermal Analysis and Calorimetry). This defines Thermal Analysis includes all the methods of measuring the sample properties while the sample temperature is program-controlled. Figure 1.
In this paper, a new set of experimental data, α V K T V, representing the partial temperature derivative of the work done by the thermal pressure of the solid, is fitted by n terms of a modified Einstein model. Experimental data show that α V K T V, not α V K T, approaches a constant value at high on the observed linear relationship of isothermal bulk modulus with Cited by: numerically using the maximum power (MP) and maximum power density (MPD) method . The Regenerative Cycle. The regenerative cycle is becoming prominent in these days of tight fuel reserves and high fuel costs. The amount of fuel needed can be reduced by the use of a regenerator in which the hot turbine exhaust.
Equations are required to determine the volumes from the geometric variables for the heat exchangers. Equations 4–9 are the equations for the volume V and area A of the cooler, heater and regenerator, respectively.. Equations 4 and 5 define the volume V k and surface area A k in the cooler. These equations use the number of cooler tubes N k, cooler length L k and cooler tube diameter D : James A. Wills, Tunde Bello-Ochende. This paper focuses on the influence of regenerator on the performance of a single‐stage looped thermoacoustic engine. Numerical simulation has firstly been carried out to investigate how the regenerator efficiency, generated acoustic power, and acoustic field in the regenerator are affected by the cross‐sectional area, regenerator length, and mesh by: 3.
