AN INVESTIGATION OF RESISTANCE AND HEAT TRANSFER DURING TURBULENT AIR FLOW IN AXIALLY SYMMETRIC CHANNELS WITH A LONGITUDINAL PRESSURE GRADIENT

Abstract

Th turbul nt boundary lay r i a flow of heate air in an axially sy metric diffuser and effuser channels with cooled walls is studied. Test data are reduced and ge eralized in parametric form. The dependences of th sh pe parameters, which characterize the shape of the velocity and temperature profile and which determine the law of friction a d heat tra fer o the longitudinal pr ure gra ient are d r i ed. A UTHOR) A -284 086 N6 +++Resistance and heat transfer characteristics during turbulent air flow in an axially symmetric channel with a longitudinal pres ure gr dient.
