Abstract
A study for both numerical and experimental aspects on low speed forced convective heat transfer near two-dimensional transverse ribs in which the walls are held at a uniform temperature is presented. The effects of aspect ratio and Reynolds number as well as the initial boundary layer thickness are examined and discussed. The numerical technique is based on a power law combined with a false stream function-vorticity form. It is found that the temperature data agree reasonably well with those taken from the experiments qualitatively. The results are further correlated by an equation of the form Nu av = 0.44(Re s) 0.465(d/s) −0.36(w/s) −0.265 .
