Numerical Study of the Velocity and Temperature Fields in a Flow-Through Reservoir

Abstract

The fluid dynamic and temperature fields in a reservoir are numerically simulated by means of a finite difference procedure. The flow in the rectangular reservoir is assumed to be two-dimensional in a vertical plane. Inflow is allowed at the surface on one end of the reservoir and outflow occurs at any depth on the opposite end. The reservoir inflow is set at a given temperature and velocity so as to simulate the thermal discharge from a power generating facility. At the surface of the reservoir wind shear, short wave and long wave radiation, evaporation, and convective heat transfer are taken into account. The effects of inflow/outflow, wind shear, and heat transfer on the reservoir are discussed.
