if an external cooling jacket is used, the requirement on valve material can be further reduced.
如在阀体外加上外冷却夹套,则可进一步降低对阀材料的要求。
secondly, two dimensional conductive model of cooling jacket was set up and numerical simulation was carried out using one dimensional results. temperature field in cooling jacket was computed.
其次建立了推力室的冷却套二维导热模型,使用数值模拟的方法和一维计算的结果,得到了冷却套的温度场。
for dirty water or sanitary sewage applications, clogging of the cooling jacket passages can easily occur due to a build-up of solids, grease, corrosion and other matter.
