• W1567337522 abstract "Based on the energy balance law and the mass balance law in thermodynamics, a mathematical model on the transient heat exchange process of the inter-cooler is estab· lished. Then a model on optimization of the cooler is proposed in which the obj::ctive function is the total entropy generation rate (TEGR), giving consideration to both the !).eat transfer and the flow resistance in the cooler. Finally, the results of the optimization on the structure size and the operating parameters are searched for the cooler. The feasibility of the simulating model and the reliability of the optimizating results have been proved by the experiments in a compressor. INTRODUCTION In order to increase the economy and reliability of multi-stage compressor during operation, studies on the inter-cooler of compressor should be. paid attention to in addition to studing the compressor itself. From the standpoint of the whole compressor system including the compressor, inter-cooler, and later-cooler, the authors have conducted the simulation of the transient heat transfer and the optimization of the structure for the inter-cooler. In combination with our previous publications1 •21 , the computer aided design for compressor system can be realized. The shell-and-tube cooler with barnes is widely used in engineering. In the present. paper, a mathematical model on the transient heat exchange of a counterflow shell-and-tube cooler has been established on the basis of the energy balance law and the mass balance law in thermodynamics. By using the flow path analysis method, the heat exchange coefficient for the shell side in the reference12l is revised, thus the accuracy of the calculation is improved. At the same time, by means of the finite difference method, the numerical solutions for the gas inside the tube, the cooling water in the shell side, and the temperature in the tube wall are obtained, and the change rule of temperature with the time and the spacial position is determined in the heat exchange period. On this basis, a model on optimization of the cooler is proposed in which the objective function is the total entropy generation rating (TEGR), giving consideration to the two important factors, that is the heat transfer and the flow resistance in the cooler, and especially emphasising its research on energy quality. Finally, the results of optimization on the structure size and the" @default.
