A STUDY OF RESISTANCE AND HEAT-EXCHANGE IN THE MOTION OF HEATED AIR IN DIFFUSORS AND MIXERS.
LIBRARY OF CONGRESS WASHINGTON D C AEROSPACE INFORMATION DIV
Experimental studies were made of resistance and heatexchange in a turbulent stream of heated air in an axisymmetric diffusor with 8 degree 4 min angle of opening, and in an axisymmetric mixer with 8 degrees angle of opening. The tests run embraced a range of numbers Re 1,688 to 8.45 .100000. The temperature of the walls of the ducts, which were cooled by water, varied from 286 to 320 K the temperature of the air stream varied from 425 to 623 degrees. M numbers were or 0.5.
