TURBULENT DIFFUSION OF MOMENTUM AND HEAT FROM A SMOOTH, PLANE BOUNDARY WITH ZERO PRESSURE GRADIENT

摘要

Results of an experimental investigation of the turbulent diffusion of momentum and heat from a smooth, plane boundary with zero pressure gradient are presented.nThe velocities have been measured with hot-wire anemometers and the Reynolds stress distribution in the boundary layer has been computed from the measurements of the crossed-hot-wire anemometers. The temperatures have been measured with thermocouples, and the trans¬ferred heat has been determined from the electrical input to the heated boundary. Data on the pertinent variables have been collected along the centerline of the boundary and at four cross-sections of the bound¬ary layer.
