| Summary: | 碩士 === 大同工學院 === 機械工程研究所 === 81 === The present study is investigate the effectiveness of direct
transfer type, crossflow heat exchanger with neither fluid
mixed due to the influnce of the aspect ratio, capacity ratio
and conductance ratio. FAM (finite analytic method) is utilized
in the two fluid flows and FDM(finite difference method)is
utilized in the separator sheet to analyze the exchanger
effectiveness.Numerical results show the comparison between he
finite analytic method and finite difference method in the
different boundary form of the insulatededge and the different
node-point in the separator sheet. The present study is also to
propose the useful modification in the finite analytic method.
Next,the optimun aspect ratio is found with various parameters
like as capacity rate and conductance ratio.
