摘要
In order to obtain the heat transfer characteristics for impingement of a strut in aero engine inlet, experiments were carried out with the use of transient thermochromic liquid crystal measurement technique in a wedge channel. The effects of jet Reynolds number, jet angle and position of outlet slot on Nusselt(Nu) number distribution were studied with the jet Reynolds number range from 6.3×103 to 15.9×103 and jet angle from 0° to 30°.The results show that the average heat transfer in the wedge channel was enhanced with the increasing Reynolds number and jet angle.The wall has a greater heat transfer when the slot near impingement inlet with the jet angle range from 0° to 15°.The Nu number of two sides of the wedge channel is asymmetric under the condition that jet angle is not vertical.When the jet angel is 30°, the nonuniform is the most obvious. The Nu number is the highest at leading edge when the jet angel is 15°.
