WINTER-REGIME THERMAL RESPONSE OF HEATED STREAMS

THE INCREASE IN WATER TEMPERATURE IN NATURAL STREAMS DUE TO WASTE HEAT DISPOSAL FROM THERMAL POWER PLANTS LEADS TO EXTENSIVE ICE-FREE REACHES DURING WINTER PERIODS. IT IS SHOWN THAT THE SURFACE HEAT EXCHANGE BETWEEN WATER AND THE ATMOSPHERE CAN BE EXPRESSED, FOR MOST PRACTICAL PURPOSES, AS A LINEAR FUNCTION OF THE WATER TEMPERATURE. USING THIS APPROXIMATION, A CLOSED-FORM SOLUTION OF THE ONE-DIMENSIONAL UNSTEADY CONVECTION-DIFFUSION EQUATION IS DEVELOPED TO PREDICT TEMPERATURE DISTRIBUTIONS IN STREAMS AND THE LENGTHS OF ICE-FREE DOWNSTREAM FROM THE THERMAL DISCHARGE SECTIONS. /ASCE/
