Method of research on heat exchange for parallel plates with low thermal conductivity in short-time processes

Temperature of coolant was measured at the input and output of an alternating regenerator. Additionally, the temperature was measured both at several points on the surface of the parallel plates and along their geometrical axis. The package of the parallel plates was used as a nozzle of the regenerator. The method of determining heat transfer coefficients was described for the side and butt end surfaces of the plates in short-time processes. The mathematical models were created for the following two non-stationary processes. The first process is convective energy transfer in heat carrier flows. The second one is the process of thermal conductivity of two-dimensional body (plate) washed cyclically by cold and hot heat carrier flows. The coefficients of cyclic heat exchange with the cold and hot heat carrier flows were obtained for the side and butt end surfaces of the plates in short-time processes.
