An experimental investigation was conducted to study convective heat transfer in
straight and curved rectangular channels of high aspect ratio that approximate plates
of infinite extent. Experiments were performed at steady state in the turbulent flow
regime with one wall held at a constant heat fiux and the opposite wall essentially
adiabatic. The effect of curvature induced secondary flow on heat transfer on the
concave and convex walls was observed by comparing Nusselt numbers for four
different configurations at several different Reynolds numbers. Significant heat transfer
enhancement was observed on the concave wall. Correlations for Nusselt number as a
function of Reynolds number were calculated for the cases studied.
