Free And Forced Convection

Combined free and forced-convection, heat-generating laminar flow inside cylindrical pipes with elements parallel to the direction of the generating body force is solved by applying the finite Fourier sine transform and finite Hankel transforms when the cross sections of the pipes are circular sectors. A numerical example is provided to show the effects of various parameters.

Free And Forced Convection

This paper describes an investigation into combined free and forced convection heat transfer for laminar water flow in horizontal tubes. The experimental data obtained do not agree with existing correlations, which relate mainly to oils. A new correlation has been derived which fits the water data to within ±8 per cent.

Good Agreement

A variational method is presented for determining fully developed velocity and temperature distributions for laminar flow in noncircular ducts. The heat addition to the fluid is taken to be uniform in the axial direction, but a variety of thermal boundary conditions are considered around the periphery of the duct cross section. Several illustrative examples are given, and comparisons are made which show good agreement with available exact solutions. These examples include ducts of rectangular and circular-sector cross sections.
