Irreversibility of Heat-Transfer Processes in Double-Flow Cells of Varying Flow Hydrodynamics

Consideration has been given to the influence of the hydrodynamics and phase state of the flows in a double-flow heat-exchange cell on the entropy production in it. For the case of the Newtonian kinetics of heat transfer in such a cell, the authors have obtained formulas for calculating the entropy production in it as a function of the heattransfer coefficient, the heat load, the temperatures, and the water equivalents of the flows in the cell.
