FLOW ANALYSIS IN POOL AND WEIR TYPE FISHWAY USING VOF METHOD

Abstract

This paper presents a 2-dimensional analysis of the flow in a pool and weir type fishway using VOF method. Because of a large influence to the result by the suitability of a different scheme of advection term in the equation of motion, the appropriateness of a numerical solution is examined by using different methods. And k-ε A turbulence model are applied to coefficient of kinematic viscosity for making the precision of a solution better. It is shown that QUICK method with k-ε A turbulence model is able to reproduce a flow precisely the most for the present.
