Abstract

When applying the energy and/or momentum equations, the velocity distribution is considered to be steady uniform and non-varying along the channel. The above assumption can be accepted if the flow is steady and nearly uniform. However, in fact that the flow is unsteady, the boundary resistance modifies the velocity distribution. Especially, in case of flow in the side channel is spatially varied flow with 3D vortex structure, the velocity distribution becomes more and more complex. The results of determining the velocity distribution coefficients including momentum correction coefficient (a₀) and kinetic energy correction coefficient (a) for spatially varied flow in the side channel is presented in this article.
