Abstract

terms of the various physical mechanisms that arise and the surface temperature was determined as a function of the ambient conditions. The yearly temperature cycle was determined from a numerical solution of the governing equation, with the eddy diffusivity taken as a function of depth and time, through the stratification profile. The stratification cycle and the variation of depth with time was also determined and compared with available temperature data. The results obtained were considered in terms of the underlying physical processes and compared with other physical models developed for the temperature cycle. The dependence of the cycle on the relevant governing parameters was also studied. The study then considered the effect of heat rejection, to the simulated water body, on the temperature cycle and on the thermal stratification. This paper discusses a numerical simulation of the heat transfer processes in a natural water body. A one-dimensional transient model was employed to study the periodic temperature cycle of the water body. The energy exchange was considered at the water surface in
