NUMERICAL EXPERIMENTS WITH LAMINAR BUOYANT DISCHARGE INTO RESERVOIRS

Abstract

Fluid flow and temperature fields in the two-dimensional vertical plane of a reservoir are numerically modeled for inflow Reynolds number R₀ in the range 100-1000 and inflow densimetric Froude number F₀ in the range 0.5-50,0. Both surface inflow and submerged inflow were studied for reservoir slopes of 45° and 90°. Numerical experiments show that the flow fields and temperature distributions in the reservoir are primarily a function of F₀, while the dependence on R₀ is implicitly coupled to F₀. The strengths and extent of recirculation of the flow fields in the reservoirs were observed to be characterized by functions that are directly proportional to l/F² ₀ and R₀.
