Abstrakt

Laminar tube flow and heat transfer for helium gas are analyzed numerically by using the compressible Navier-Stokes, energy, and continuity equations in finite difference form. Both radial and axial property variations are considered. The radial as well as the axial velocity are retained in the equations; the only assumptions made in the equations are the usual boundary-layer assumptions. The heat flux at the wall and the initial velocity and temperature profiles are taken to be uniform. The effects of both heat flux and Mach number on the Nusselt number and friction correlations are obtained.
