| Abstract: | Based on numerical finite difference method,the rotor's peripheral side spread in the rotor's rotary velocity direction and set grids between the matrix element and the fluid based on the energy balance equation between the matrix element and the stream.In addition,by combining the air-leakage factor and using an improved Gauss-Sidel arithmetic for iteration,a program is developed to calculate the heat transfer performance of quad-sector air-preheater.The process is realized by FORTRAN.One can obtain metal ... |
