Numerical Simulation of Heat Transfer Characteristics of Dimpled Plate

Abstract:

Designed a new type of plate heat exchanger-dimpled plate heat exchanger, then conducted a three-dimensional numerical simulation on flow, heat transfer and resistance characteristics of 15 kinds of different sizes dimpled plate heat exchangers by Fluent software，obtains the impact of the dimples geometric parameters such as dimple diameter, dimple spacing, dimple height on the heat transfer and flow characteristics. The results show that in different Reynolds number, dimple diameter, dimple spacing and dimple height on the effect of the dimple plate heat transfer efficiency is quite similar, and the impact becomes increasingly evident with the Reynolds numbers increasing. The combined effect of plate heat exchanger is best when dimple diameter, dimple spacing, dimple height are separately 12mm, 21mm, 4mm in the 15 kinds of different combination dimpled plates.
