You need to make that region as a separate part BEFORE you start a new flow simulation. The simulation will not work if you create the rotation region while you are editing flow simulation parameters. Only if I check it for penetrating, it says something is off.ĮDIT 2: I solved the issue. The CFX solver has advanced features to model the flow through interfaces between the stationary and rotating fluid zones. The next step was to apply boundary conditions, a flow rate of 63. It is the best in class solver for simulating rotating machinery. simulation to recognise that the impeller is rotating. Other people who had issues with this feature had issues with not being able to choose the right part, and somehow noone had this problem.ĮDIT: When I use the option to check geometry in Flow Simulation tab, it says the geometry is OK. Simulation set-up in CFX-Pre: CFX is the solver of choice to simulate the fluid flow in the pump. Turbulence is modelled with k- turbulence model. No matter what I try to do, I cannot make it work - as ignoring it prevents me from making a mesh and continuing with the simulation. SOLIDWORKS Flow Simulation is an intuitive Computational Fluid Dynamics (CFD) solution embedded within SOLIDWORKS 3D CAD that enables you to quickly and easily simulate liquid and gas flows through and around your designs to calculate product performance and capabilities. The incompressible flow through the rotating impeller is solved with a moving frame of reference with constant rotational speed.3-D incompressible Navier-Strokes equations with the rotational force term are solved to analyze the flow in centrifugal pump. I did all of the boundary conditions, goals and input data without fail up until the rotating region.įor some reason, the program detects penetration of parts - the rotation region extrude penetrates my turbine. I have been following this Solidworks tutorial on youtube: (Around 1:40:00 the person makes that extrude, then proceeds with the simulation without errors). I have created a model of a bladeless fan, a turbine and the extrude that would serve as rotation region for my cfd simulation. I added a cylindirical area around impeller and applied rotating frame.
Select Fluid Subdomain, it goes through the model nicely 5. Select the rotating region, a cylinder body which covers the whole impeller 4.
Hi! I have an issue with the operation mentioned above, and I can't seem to find an answer. The picture that I attached is showing a pump which I am trying to find the flow velocity near blade surfaces. Use the Wizard tool to create new simulation project (internal, local rotating region, water, lowest resolution) 3.
