Given parameters: the inlet and outlet temperatures of the shell-side steam are 205 and 95 degrees Celsius, respectively. The operating pressure is 0.75 Mpa. The inlet and outlet temperatures of the tube-side cooling water are 38 and 97 degrees Celsius respectively. The operating pressure is 1.6 Mpa. The cooling water flow rate is 120 t/h. This is my graduation project. I’ve already done it by referring to what’s available online. But I recently heard someone say that it should be calculated in segments. Is it still water vapor at the shell side outlet? Is segmentation not necessary? If there is also steam, which formula should be used to calculate the convective heat transfer coefficient in the shell side? The flow velocity is assumed to be 50 m/s in all calculations. Is it inappropriate? Could someone with expertise give some advice? How exactly to do it?
According to calculations using the HYSYS+HTRI software, the outlet of the shell side will definitely contain condensate, as the latent heat of steam is utilized. What are you trying to do, cooling water outlet 97? A flow rate of 50 m/s is on the high side. Is the graduation project just about doing such simple calculations?
No, it’s to make a U-tube heat exchanger. Forgot to mention it
