An approach to calculating turbulent flows in the nearwall region
Abstract
A one equation turbulent kinetic energy model which accounts for the low Reynolds number effect is used with a specified length scale to calculate turbulent transport in the near wall region. Outside this region a two equation turbulence model is employed. The procedure is used to predict turbulent flow in a pipe with heat transfer and can be used for more complicated flows. An iteration procedure was introduced to decrease the large number of grid points otherwise required for such work. The hydrodynamic and heat transfer results for the whole range of laminar Prandtl number fluids are in good agreement with experimental data.
