Surface Heat Exchange and Hydrothermal Analysis

Part of the Marine Science book series (MR, volume 7)


The seven physical mechanisms of surface heat exchange are discussed and their summary as the net rate of surface heat exchange is defined. The algebraic formulation of the net rate of surface heat exchange into an equilibrium temperature and a coefficient of surface heat exchange is presented. The definitions of the equilibrium temperature and coefficient of surface heat exchange lead to the concept of excess temperature resulting from man-made heat sources.

The incorporation of surface heat exchange into hydrothermal analyses is presented in terms of three spatial scales and three spatial dimensions over which heat transport can take place. The relative importance of surface heat exchange to initial discharge mixing, the intermediate scale of advection and dispersion, and large scale whole waterbody processes is formulated and presented. The significance of surface heat exchange in time varying temperature problems is also discussed.
