Effectiveness of a Thermal Air Shield in the Case of Pulsed Blowing through a Slot at an Angle of 30 Degree
摘要
Abstract
The paper focuses on the comparative study into the effectiveness of film cooling of a flat wall surface by pulsed blowing of secondary airflow through a slot inclined at an angle of 30 deg to the main flow. The impact intensity of pulsation affecting the development of the heat shield was analyzed at different values of the blowing ratio.
