A mathematical model for investigating the processes in 
regenerative heat exchangers is described. A finite-difference scheme 
of numerical integration is proposed for solving the conjugate problem 
on unsteady heat exchange between one-dimensional flows and a two-dimensional 
matrix wall. Test calculations were compared with the known data of 
other authors. The quasi-stationary and dynamic processes in a gas-turbine 
plant regenerator with a matrix packed with gauzes have been investigated. 
The optimum design parameters of such a regenerator and rotational 
speeds of its rotor that which provide a maximum heat efficiency of 
the regenerator at a minimum aerodynamic drag in it have been determined.
