The density obtained from process simulation differs from that obtained through Analysis
Thread Content
I would like to ask everyone for advice. When calculating the density of a certain component, I encountered a strange issue: the density obtained from process simulation was different from the density obtained through Analysis. Further research found that the software uses the Rackett equation (equation number: 0) for process simulation, whereas it uses the DIPPR equation (equation number: 105) for Analysis. And I hope the DIPPR equation can be used for process simulation. The process is very simple: it consists of just a heater, with material flowing in and out, and there is only one component.
Just change the route in the method
