MOMENTUM AND HEAT TRANSFER TO A FLUID FLOWING TURBULENTLY IN A PIPE
A mathematical model is presented for the prediction of heat-transfer coefficients for fully developed turbulent flow of fluids in circular pipes by analogy to the transfer of momentum. An empirical velocity-distribution equation derived from experimental data is presented for use in the analogy model. Heat- transfer coefficients for fluids with Prandtl numbers ranging from 0.01 to 100 and Reynolds numbers ranging from 5 x 10/sup 3/ to 10/sup 7/ are presented in tabular and graphical forms for both the case of constant heat flux at the pipe wall and the case of constant temperature at the pipe wall. The calculated heat- transfer coefficients are compared with existing experimental data, and a discussion of the parameters affecting the heat-transfer characteristics of fluids in turbulent motion in circular pipes is presented.
