LOCAL HEAT TRANSFER AND RECOVERY TEMPERATURES ON A YAWED CYLINDER AT A MACH NUMBER OF 4.15 AND HIGH REYNOLDS NUMBERS

摘要

Local heat transfer, equilibrium temperatures, and wall static pressures have been measured, on a circular cylinder at yaw angles of 0°, 10°, 20°, 40°, and 60°. The Reynolds number range of the tests was from 1X106 to 4X106 based on cylinder diameter.nIncreasing the yaw angle from 0° to 40° increased the stagnation-line heat-transfer coefficients by 100 to 180 percent. A further increase in yaw angle to 60° caused, a 40-percent decrease in stagnation-line heat-transfer coefficients.
