The aerodynamic and heat-transfer characteristics for flow over an upstream-facing cylindrical cup simulating a parachute geometry were studied. It was found that: (1) The pressure on the bottom of the cup increases as the depth of the cup increases. (2) An increase in the free-stream turbulence level increases the aerodynamic heat transfer significantly. (3) The heat transfer front the bottom of the cup decreases monotonically as the depth of the cup increases. (4) The effect of suction at the cup bottom is to equalize the pressure distribution and to increase the heat transfer.
