要約

The results of numerical simulation and optimization of the design and operational characteristics of heat exchangers — heat utilizers of liquid-gas type are presented. Minimum production of entropy has been taken to be one of the criteria. The effect of heat-carrier rates and the change of the thermal load on the thermodynamic heat-utilizer efficiency is shown. Optimal regularities of changing heat-exchanger temperatures in the countercurrent heat exchange apparatus in different operating modes and at different design parameters have been determined. Applied solutions of heat-utilizer optimization by nonequilibrium thermodynamic methods have been analyzed.
