Approximate Dynamic Analysis of Crossflow Heat Exchanger by the Method of Weighted Residuals

抄録

In this paper approximate lumped parameter models by the method of Weighted Residuals (MWR) are given for a cross flow heat exchanger and compared favourably with the Finite Difference Method (FDM). Two kinds of weighting function (Collocation Method). Several numerical examples show that the FDM model must be a considerablly higher order to secure the same accuracy as the MWR model does to simulate the static and dynamic characteristics.
