가스터빈블레이드에서 일렬의 제트에 의한 막냉각특성 연구
Film Cooling by a Row of Jets in a Gas Turbine Blade
초록
The objective of the present study is to predict the film cooling effectiveness by a row of holes at various injection ratios and injection angles. Numerical calculations have been performed to investigate the characteristics of flow and temperature distributions in a region near the down-stream of injection hole including the region of adverse pressure gradient. The elliptic turbulent 3-dimensional governing equations with variable thermal properties using the low-Reynolds number k-
