    Centrifugal Pump Cosmos Floworks Problem

    Hello, I found that when using the external analysis you do not need to assign any boundary conditions, which in turn make the analysis far faster. In my example the scroll casing was not closed, there were opening at inlet and outlet. I had to create lids to measure the volume rate, these are...

    Centrifugal Pump Cosmos Floworks Problem

    Hello, I think this is quite common and is due to part of your design. The COSMOS Tutorial PDF file explains this on page 4-10 the tutorial is usually located in: C:\Program Files\SolidWorks\COSMOS\FloWorks\lang\english\Docs Also did you let the analysis run for the complete duration? These...

    Centrifugal Pump Cosmos Floworks Problem

    Hello, Yes, you need to put a negative in front. You cannot stop the fluid rotating in this instance, if you want the fluid to flow uniformly into the impeller i think you would be better using the local region. You have to create a simple part which covers all the dimensions of the impeller and...

    Centrifugal Pump Cosmos Floworks Problem

    Hello, When using global rotating everything is assumed to rotate so the impeller will be rotating but so will the casing, airflow and everything else you have in the model, you have to specify the items which are stationary by assigning them as real wall, stators in boundary conditions. Also...

    Centrifugal Pump Cosmos Floworks Problem

    Hello, Thanks for you reply, sorry about my late response. I have looked at the tutorial and also had a look through the other files. The pump example uses the global rotating feature, I think that I need to use the local rotating feature to solve my problem. When using the local rotating...

    Centrifugal Pump Cosmos Floworks Problem

    Hello, Thanks for your reply. Where can I find this tutorial? I have done a similar example which uses the global rotating option, this was taken from the PDF file in the Floworks help files. Being as the impeller is offset in the casing, do I have to create a rotating region that is big enough...

    Centrifugal Pump Cosmos Floworks Problem

    I am very new to Floworks and have created a centrifugal pump that consists of an impeller and a scroll casing. I need to assign an environmental pressure at inlet and outlet and let Floworks tell me the flow rates. I am trying to simulate the fluid flow in the pump but I am having a few...
