Summary

COMPLEMENTARY HEAT TRANSFER, PRESSURE DISTRIBUTION, AND FLOW VISUALIZATION EXPERIMENTS WERE PERFORMED TO INVESTIGATE THE EFFECT OF YAW ON BOTH STAGGERED AND IN-LINE TUBE BANKS. AIR WAS THE HEAT TRANSFER FLUID. THE VISUALIZATION EXPERIMENTS REVEALED THAT YAW MARKEDLY AFFECTED THE MANNER IN WHICH THE FLOW IMPINGED ON THE TUBES OF THE IN-LINE ARRAY, WITH A LESSER EFFECT OF YAW ON THE FLOW FIELD IN THE STAGGERED ARRAY. THE NUSSELT NUMBER GENERALLY DECREASED AS THE ANGLE OF YAW INCREASED. THE YAW EFFECT WAS WELL CORRELATED FOR THE STAGGERED ARRAY, BUT NOT SO WELL FOR THE IN-LINE ARRAY. THE PRESSURE DROP DECREASED WITH INCREASINGYAW.
