Characteristics of a density current in a cooling lake sidearm

A convective flow is generated in the sidearm of a lake due to surface cool ing. In this paper, steady, incompressible, and 2D Row in a horizontal side arm having constant width is analyzed. The vertical acceleration terms and the variation of the temperature function along the sidearm (which were neg lected in the previous studies) are considered. The equations governing the distributions of velocity and temperature were developed, then solved nume rically by using a "shooting technique" and Runge-Kutta method. The numeric al results were compared with the available held data for validation.
