Abstract : The features of convection heat transfer in liquid and gas eddy flow were examined. The influence of pressure and degree of vorticity on the intensity of heat transfer in cylindrical chambers were also investigated. Results indicated that the relative increase in convection heat transfer in gas eddy flow is a function only of the degree of vorticity. Convection heat transfer in gas eddy flow is independent of pressure. The validity is proved of treating eddyflow heat transfer in the entrance section of a tube as heat transfer to a longitudinally streamlined plate. (Author)
