Heat Transfer Characteristics of Heat-Storage-Type Heat Transfer Elements for Gas Turbines

抄録

Many papers have described heat transfer in a regenerator core. We tried to obtain an approximate solution of original partial differential equations dealing with heat transfer between gas and core. The exact solution of the original equation is so complicated that the equations were converted to simultaneous ordinary differential equations by using the finite difference form. We obtained the approximate solution described here and inspected it for accuracy. We then applied it to the evaluation of the heat transfer rate of a model core. This method was compared to the maximum slope method, and the precision of the calculated results was verified.
