Study on the heat transfer performance of honeycomb plate with different parameters by orthogonal design

Using CFD software,it was compared the performance of honeycomb on different plate pitch,dimple diameter,dimple depth and dimple horizontal pitch.It indicoded that,with the increase of Re,Nu was exponentially increased,f,Nu/Nu0,η were exponentially decreased,and f/f0 was slightly decreased overall within a certain range.The flow channel height had rarely effect on various performance.Nu/Nu0 and f/f0 were decreased with the increase of dimple pitch P,and were increased with the increase of dimple print diameter d;the increase of dimple depth Hd brought the firstly increase and following decrease of Nu/Nu0 and f/f0;η is slightly increased with the increase of P and d,and the increase of dimple depth Hd brought the decrease of η.By means of orthogonal,it fitted a flow and heat transfer performance relationship for the structure of honeycombed plate with dimpled surface.
