Type of article: Article

Summary

THE MALDISTRIBUTION WAS CREATED BY A PARTIAL BLOCKAGE OF THE INLET SECTION. BASELINE EXPERIMENTS FOR UNIFORMLY DISTRIBUTED INLET FLOW WERE ALSO CARRIED OUT. THE EXPERIMENTS SPANNED AN ORDER OF MAGNITUDE RANGE IN THE REYNOLDS NUMBER. ON THE WHOLE, THE INLET-SECTION FLOW MALDISTRIBUTION TENDS TO ENHANCE THE HEAT TRANSFER AT A GIVEN REYNOLDS NUMBER, WITH AN ACCOMPANYING ADDITIONAL PRESSURE DROP OF ABOUT 2 1/2 VELOCITY HEADS. ENHANCEMENTS ARE ENCOUNTERED IN THE FIRST SEVERAL ROWS IN THE CORRIDOR DOWNSTREAM OF THE UNBLOCKED PORTION OF THE INLET SECTION AND REDUCTIONS ARE CONFINED TO A NARROW ALLEY BEHIND THE BLOCKAGE.
