EFFECTS OF COMPUTATIONAL GRIDS ON NUMERICAL SIMULATION OF TRANSONIC TURBINE CASCADE FLOWFIELDS
천음속 터빈 익렬유동의 수치해석에서의 계산격자점 영향
Abstract
Numerical investigations have been performed to examine the effects of the computational grids on the prediction of the flow characteristics inside the turbine cascades. Three kinds of grid system based on H-type grid are applied to the high-turning transonic turbine rotor blades and comparisons with the experimental data and the numerical results of each grid structure have been done. In addition, the grid sensitivity on the estimation of the blade performances has been investigated.
