BR0.3 type plate heat exchanger was used for the experiment. Through the test platform of plate heat exchanger, a large number of experiments have been done in different mixed mode but the same passageway. By the linear fitting method and the analysis of the data, the formula of flow resistance which fit at any mixed mode is obtained, it solves the problem of calculating flow resistance and has a great help for engineering calculation.

In general the conventional plate heat exchanger has good heat transfer performance on the one hand and high pressure drop on the other hand. In order to deal with this dilemma, a novel plate heat exchanger with compound corrugations is proposed in this paper. Comparisons with the traditional plate heat exchanger indicate that the new heat exchanger can reduce flow resistance and simultaneously improve its heat transfer performance. The heat-transfer oil with a relatively high dynamic viscosity is selected as the working fluid. The performance in the newly-proposed plate heat exchanger with compound corrugations in the condition of low Reynolds number and high Prandtl number is numerically investigated. In the process of numerical simulations, variations are made on one geometric parameter of the plates and keep invariant for the others. Through comparisons on the j-factor, the friction factor and their ratio j/f for various plate geometries, the influence of geometry parameters on heat transfer performance, flow resistance characteristics and comprehensive heat exchanger performance is thoroughly examined. Based on numerical results, the geometric parameters which have significant impact on heat transfer and flow resistance of the proposed plate heat exchanger are determined. And the Nusselt number and friction factor correlations of the plate heat exchanger with compound corrugations are obtained, which are applicable for the laminar flow mode when the working fluid is with low Reynolds number and high Prandtl number.
