How to simulate the shell-side pressure drop in HTRI?
Thread Content
The pressure drop across the shell side of the heat exchanger in operation is currently 1 kilogram; I want to use HTRI to determine what flow rate would be required to reduce this pressure drop to 20 kPa. How to simulate the shell side pressure drop in HTRI?
It’s very simple; just try it a few times on your own and you’ll figure it out Just keep the tube-side flow rate setting, the inlet and outlet temperature settings, and the shell-side inlet and outlet temperature settings unchanged; don’t change the structure either. By simply adjusting the shell-side flow rate, you can figure it out easily, right? The principle should be that the lower the shell-side flow rate, the lower the velocity and the smaller the pressure drop. Furthermore, the angle at which the heat exchange tubes are arranged also has a significant impact on the pressure drop on the shell side; a 90° arrangement results in the lowest pressure drop on the shell side.
Enter the media in the tube and shell sides, the operating conditions, and the equipment structure into HTRI, and then the pressure drop on the shell side can be simulated. If a lower pressure drop is desired, parameters such as the equipment diameter can be adjusted to reduce it
