I am trying to simulate airflow of a fan in a enclosure. The fan that I am trying to model is a HVLS fan and it is 12 feet in diameter. I asked the company that produces it and they said they don't have fan curves for HVLS fans. Is there any other way to model the fan without a fan curve?
If you know how much volume rate flow (example 1000 M^3) , you can apply as a boundry condition on a simple face
HVLS fans work in free air and main purpose is to move air in the area creating pressure but w/o special requirements. It may be hard to find fan curve but anyway you should be able to get value of flow per time period (m3/h or other) and then simulate it as i.e. internal fan with no pressure drop.
Or you can model fan itself but it may be harder :-)
Let us know what exactly you want to check
Ciao!
Hi Kamil thanks for your reply! For my project I am trying to visualize the airflow caused by two HVLS fans in the facility to identify potential areas of stagnate air. I am also trying to see the temperature cut plot within the facility.
Please check the total flow of HVLS with producer and model it as a thin cylinder -> exclude this geometry from simulation -> use the geometry for defining internal fan. In engineering database define HVLS as fan with stable flow independently from pressure drop.
I hope it helps.
Ok, thanks! So is there any advantage in actually modeling the fan?
If you will model it as it is you'll simulate its behaviour with impact on environment. If you're interested only on effect (facility air flow) skip it what, btw, will do your CFD faster. Concentrate on goals :-)
Gotcha, thanks!
Mr. David
Could yo show your fan image, there may be a case of the same? otherwise it could increase knowledge for beginners like me.
Thank you
