A beginner in heat exchangers seeking help
Thread Content
Hello, experts. I am a student currently in school. When designing heat exchangers, both the fluid in the tube side and that in the shell side are two-phase flows, with the gas phase being the dominant component; the liquid phase makes up only 0.8% of the total flow. I’m not sure whether this liquid phase can be ignored. If two-phase flow is to be taken into account, how can the flow pattern be determined? It depends on the gas velocity, right? The hot fluid is syngas at a pressure of 5 MPa; what would be an appropriate gas flow rate?
Depends on the degree of impact on heat transfer
I don’t know the flow pattern either; how can I determine its impact on heat transfer efficiency?
Generally, the margin left for calculation is much larger than 0.8%, so it can be ignored.
