Type of article: Article

Summary

THE CLEARANCE WAS VARIED PARAMETRICALLY, STARTING WITH THE NO-CLEARANCE CASE ; PARAMETRIC VARIATIONS OF THE FIN HEIGHT AND OF THE RATE OF FLUID FLOW THROUGH THE ARRAY WERE ALSO CARRIED OUT. AIR WAS THE WORKING FLUID, AND THE FLOW WAS TURBULENT. THE FULLY DEVELOPED HEAT TRANSFER COEFFICIENTS WERE COMPARED UNDER THE CONDITION OF EQUAL AIR FLOW RATE, AND SUBSTANTIAL CLEARANCE-RELATED REDUCTIONS WERE FOUND TO EXIST. FOR CLEARANCES EQUAL TO 10, 20,AND 30 PERCENT OF THE IN HEIGHT, THE HEAT TRANSFER COEFFICIENTS WERE 85, 74,AN 4 PERCENT OF THOSE FOR THE NO-CLEARANCE CASE. THE RATIO OF THE WITH-CLEARANCE AND NO-CLEARANCE HEAT TRANSFER COEFFICIENTS WAS A FUNCTION ONLY OF THE CLEARANCE-TO-FIN-HEIGHT RATIO.
