Heat transfer characteristics of an unsaturated light clay bed coupled to a heat pump

摘要: A brief summary of the simplified continuity, momentum and energy equations that describe heat mass transfer through unsaturated soil is presented. Classifications water hydrodynamic laws governing flow are discussed. detailed description an experimental investigation was conducted to evaluate certain physical thermal properties also included. Specifically, experiment determine conductivity moist as a function content. Another study temperature profiles around source embedded in bed light clay, results which presented shown be close agreement with analytically predicted values. The effects various processes well influence motion fluids on earth Heat diffusion into by conduction predominant early stages heating while liquid contributes during intermediate times gas become significant later drying. The contribution convective transport increases becomes equal at moderately high temperatures. Finally, ‘effective’ or ‘equivalent’ determined. This value helps characterize behaviour purely conductive medium.
