H. Abbassi et al., Numerical investigation of forced convection in a plane channel with a built-in triangular prism, INT J TH SC, 40(7), 2001, pp. 649-658
Structure of laminar flow and heat transfer, in a two-dimensional horizonta
l channel differentially heated, with a builtin triangular prism is investi
gated from the numerical solutions of complete Navier-Stokes and energy equ
ations. The numerical scheme is based on Control Volume Finite-Element Meth
od with the SIMPLER algorithm for pressure-velocity coupling. Many standard
test flows are successfully simulated. Results are obtained for Reynolds n
umber ranging from 20 to 250 at Pr = 0.71 with constant physical properties
. The flow is especially studied in details for two Reynolds numbers, Re =
30 as a sample of the symmetric flow, and Re = 100 as a sample for the peri
odic flow. Results are presented to show how the presence of such bluff bod
y affects the flow pattern and the heat transfer from the hot bottom plate
to the flow in both cases, symmetric and periodic flows. (C) 2001 Editions
