Buoyancy effects in thermally stratified open-channel flow
Abstract
The method of expansion of successive approximations for investigating the detailed flow behavior resulting from the injection of a heated effluent flow without excess momentum at the surface of a cooler ambient open channel flow. A perturbation procedure was carried out to solve numerically the convective-diffusion equation and the equations of motion simultaneously by the modified Hartree-Womersley method. These equations were solved with simulated experimental entrance conditions for the zeroth order density and the first order velocity perturbations. A set of controlled flume experiments was also conducted to obtain data for comparison with and verification of the numerical results. The selected flows covered the range from weakly to strongly stratified flows.
