Simulation of air-cooling in Hysys?
Thread Content
During the simulation of the air cooler in Hysys: normally, the pressure drop of air is only 98–196 Pa, but in the model I created the pressure drop is much higher, at several dozen KPa. As a result, the stream after passing through the air cooler ends up with negative pressure. I would like to ask where I might have made a mistake in the settings
If you want help, you should provide detailed data – don’t let others guess! After all, everyone is helping others in their spare time; please don’t waste everyone’s time. Please upload the simulation file so we can see if we can help you find the cause!
Try setting its conductivity to a lower value....
Typically, simulations only take into account the pressure drop across the equipment, not that across the pipes; therefore, when designing the pressure drop for the equipment, a higher value is usually assigned. This approach takes into account the losses in the pipes as well as provides a design margin. When I conduct simulations personally, I usually set the pressure drop of the air cooler to within 10 kPa.
I’m working on an air cooler in a dynamic model; I haven’t had time to take a look at it yet. Thanks in advance to the original poster: victory:
