PRO严格换热器模拟的疑惑...？ 在利用htfs+对一个水——水物系管壳式换热器（bem）换热模拟成功后，想利用pro严格换热器模型进行验证。 出现以下错误提示： 2 error(s), 0 warning(s), and 0 message(s) detected: *** error *** unit 1, 'e1' - methods for transport properties are required for shell-side calculations, but are missing from thermodynamic method set "nrtl01". *** error *** unit 1, 'e1' - methods for transport properties are required for tube-side calculations, but are missing from thermodynamic method set "nrtl01". 以前并未用严格换热器进行核算模拟。对这个错误无法理解和有效的解决。 望有经验者驻足 指点迷津。。。。。 谢谢查看更多
帮忙理解下？ depending on the material thickness, expressed in micrometer thickness loss which shall be reduced from the surface to be pickled, a difference shall be made between weak and strong pickling solutions. 材料的厚度是关键, 用微米计的厚度损失应该是因盐水浸泡表面所致,盐水的强度大小对厚度减小也会不同效果.查看更多
