Abstract
Bubble plate heat exchanger is a new type heat exchanger. The influence of the plate geometric parameters on the flow and heat transfer is unclear so far. Based on the principle of multi-field synergy, the influence of the plate geometric parameters on the flow and heat transfer is studied numerically. It is find that when the unit length increases or the width decreases, the friction factor fdecreases, performance evaluation parameters PEC increases; when the inclination angle of the unit body relative to the main flow direction is 90°, the factor fobtain the minimum value, PEC obtain the maximum value. The results can be applied to the optimization of the bubble plate heat transfer element and the plate design.
