Hai everyone,

could anyone tell me the way to obtain the thrust of MARINE propeller by using the flow simulation of solidworks?

Also, how to calculate the fluid domain that is suitable for my simulation works?

please help.

thank you.

Hi Wernyu, we completed this type of project only a couple months ago for a customer. The results actually came out very close to what they were expecting once they completed the physical testing.

For the thrust, similar to the tutorials on obtaining drag, you simply need to select ALL of the faces of the propeller and choose the force component in the direction of flow. That will provide you the thrust value.

For fluid domain, check the SolidWorks knowledgebase. There is a good article on computational domain for aerodynamic flow. The pointers are basically the same. The computational domain should be large enough that the main flow does not cross a boundary condition. Start with 2 diameters to the top and side and front and 4 in the back and go from there. A really coarse mesh will help with this.
