内容記述 | For blunt-nosed, ramped flat plates at angles of attack 0 deg, 20 deg, 30 deg, and 35 deg, heat transfer and flow field around compression ramp have been investigated experimentally based on infrared thermography measurement and schlieren photograph observation in the NAL 1.27 m hypersonic wind tunnel at M(sub infinity) = 10.0 and Re(sub infinity) = 1.5-2.3 x 10(exp 6)/m. Comparisons with CFD (Computational Fluid Dynamics) using NAL codes were also made for examination and comparison of the flow fields and the magnitude of heat transfer. The experimental results showed the increase of heat transfer on the flat plate upstream of corner and on the ramp when the leading-edge is blunt. However, for high angle of attack case, the reduction of peak heating on the ramp with increasing leading-edge bluntness which may caused by shock/shock interaction was observed. An analytical study to obtain a single correlation for the measured heat transfer along the plates showed that the ratio x/r(sub n) of x distance from leading-edge and nose radius, nose radius Reynolds number and viscous parameter based on local flow condition are dominant similarity parameters for heat transfer distribution on ramp down stream of reattachment as well as on flat plate part upstream of ramp corner except small bluntness case. | |||||
