A STUDY OF RESISTANCE AND HEAT-EXCHANGE IN THE MOTION OF HEATED AIR IN DIFFUSORS AND MIXERS.

Abstract

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.
