简介:当为multicomponent混合物模仿或设计板热exchangers时,大多数设计者经常与怎么选择或估计物理性质参数和希望有能被采用的一个可靠数据库上的问题被困惑。商业代码HYSYS供应为them.This工作的超过1500种纯物质和超过16000个二进制系数上的物理性质包裹简短基于在内部板热exchanger模拟代码和HYSYS包裹之间的微软部件对象模型(COM)介绍了一个有效通讯接口。一个定做的HYSYS-COM接口的应用程序显示出高效率,例如为评估每条过程溪流的性质需要的时间的重要减小。这个自动化方法能方便地被扩大为象热转移,列,和另外的设备那样的任何特定的操作设备推进优化学习。
