Seeking help with HTFS and HTRI problems
Thread Content
In both the TASC module of HTFS (I am using TASC5.0) and the shell-and-tube heat exchanger module of HTRI, there is no O-shaped shell as mentioned in point 151. In TASC5.0, the shell-side inlet pipe can be specified as VAPOR BELT; does this yield the same effect as an O-shaped structure? How should the external flow guide cylinder structure be entered in HTRI? Please advise
Both HTFS and HTRI are designed in accordance with the TEMA standards; they do not include O-shaped shells. The external flow guides serve to enhance heat transfer and, at the same time, to prevent erosion. They also facilitate installation in cases where large-diameter inlets and outlets are present. ““VAPOR BELT” is an option within the scouring settings; it is related to the external flow guidance but should differ from the O-shaped shell. HTRI also has a similar option. The above are my personal insights; please feel free to offer any suggestions regarding any shortcomings or inaccuracies. If there really is no other option, could we consider using an E-type housing as a substitute?
Yes, flow guidance should simply involve making full use of the heat exchange area; using an E-shaped shell is a good solution
