求助换热器设计问题？ 1、 空气的入口流速是不是偏高，我自己算约32.5m/s左右。但是htri软件怎么才提示为16.67m/s的进口流速 (Yes. You are right. I made a mistake. So please revise inlet/outlet nozzle Number at each position from 2 to 1.) 2、 壳测的压降取5KPa左右的画还能否可以设计，因为这台设备要求压降要小一些 (Allowable pressure drop 5 Kpa is too tight to design. If this is a totally new design, it's better to increase allowable pressure drop. Maybe higher allowable pressure drop should increase loop pump head. It should be more economical to increase heat exchanger allowable pressure drop. If 5kpa has to be kept, 4 shells in parallel about 1000 X 6000 should be needed. So you can make judgement. Normally heat exchangers can use 10% of operating pressure.) 3、 折流板的切口方向，在图上看着像垂直切的，为什么不水平切那？因为壳测为单向流体 (Parallel Baffle Cut for high velocity gas) 4、 管内的流速取1m/s左右是不是偏高了，常轨能取这么高么？我没有经验 (Cooling Water in tube velocity recommended 1~3m/s. If lower than 1 m/s, it should be easy to fouling.) 5、最后我看htri提示有震动（好像是声震），这个对设计没影响么？ 5) acoustic vibration warning: shell side should install anti-resonatic baffles under shell side inlet nozzles. v 查看更多
