ABSTRACT

This study is to develop a computer aided heat exchanger design system, which provides a user friendly interface. Combined with Delphi’s interactive operation mode and Taguchi Method can enhance the design capability and shorten the design time. The final design will be the one with total minimal pressure drop within the space restriction. This paper is to investigates the influences of the heat exchanger parameters, such as pass, tube lengths, tube thickness, inter-tube distance, tube arrangement way and the baffle spacing for total pressure drops. The proper selection of the controlling factors, the determination of the working levels and the orthogonal array to carry on the system regulation plan are in accordance with the rules of the Taguchi Methods. The design parameters for the least total pressure drop are then obtained. The influent parameter, form the most to the least are tube arrangement way, tube lengths, inter-tube distance, pass, baffle spacing, tube thickness.
