Simulation calculation of heat exchangers
Thread Content
In the simulation calculations of heat exchangers, does it have an impact on the simulation results if the molecular weight of the mixture is not specified in the flow data? Also, I only provide the property parameters at various temperature points under the feed pressure; since there is pressure present, the flow parameters at those temperature points at the outlet are left unspecified. Does this affect the simulation results? I’m a beginner... looking forward to an answer.
I’m not sure which heat transfer software you used for the calculations; I’ll talk about HTRI here. First of all, the molecular weight of the default mixture has little impact, as there are mixtures whose composition is even unknown. It’s also possible to define one’s own components, even when the molecular weight of the mixture is unknown； Second: You have only provided the property parameters for the inlet, but not those for the outlet. If you look at the method used by HTRI to calculate properties, you’ll realize that even the simplest approach requires property parameters for both the inlet and outlet points; providing only the inlet parameters will certainly have an impact.
