Simulation and Calculation of Multi-Flow, Multistage Systems of Heat Exchangers

Abstract

A matrix model of multiflow, multistage heat-exchange systems each stage of which may possess an arbitrary number of input and output flows, is developed. The solutions of the equations of the model are obtained and analyzed and the reliability and validity of the proposed approach demonstrated. The results may be used to increase the level of validity of calculations of systems of multiflow heat exchangers and to create computersimulators and software programs for optimization of the regimes of technological systems.
