碩士 === 東海大學 === 化學工程學系 === 88 === In industrial processes , most operations operated by a chemical engineer will involve with energy exchange . And the energy usually is performed in heat form . So the heat transfer instrument is important in industrial operations . The ways , which the fluid flow through a heat exchanger , are parallel-flow , counter-flow and crossflow . Our research is the crossflow heat exchanger in unsteady state . The crossflow heat exchanger usually be applied in heating or cooling gas . So the research in gas thruogh a crossflow heat exchanger is numerous . The main purpose of this research is to analyze the unsteady state plate type crossflow heat exchanger with finite difference numerical method . We discuss the unsteady state temperature distributions with different parameter which are stated in this study .
