Heat transfer of rotary ceramic regenerators in transient mode for gas turbine.

We continuously tried to obtain a theoretical solution of equation from our published paper. An exact solution of original equation described the heat tranfer between a core and working fluids in a rotary regenerator with given boundary and initial conditions, is so complicate that the equation were convented to simultanious ordinary differential equation by using finite difference form in respect to the position. The approximate solution is shown in here and we have got transient temperatures of working fluids and the core from above solution and an effectiveness of rotary heat exchanger.
