Arbitrary Water Pumpe

Using cyclic patches for modelling a pressure drop

€60,00

Simplifications are used in computational fluid dynamics applications almost in every scenario. In most cases, special regions are not of main interest. An example is given in the following training case, in which a water pump (which is just generating a pressure drop) is removed and replaced by a 1D cyclic boundary condition. The simplification leads to less numerical cells and therefore a reduction of computational costs. Discount of 50% possible.


  • Description
  • REVIEWS
The generation of cyclic boundary patches can be used for periodic analysis as well as for particular applications such as modeling a fan or pump. Here, simply a pressure drop is applied between the patches. Based on the pressure momentum coupling, the fluid will accelerate based on the set-up. The case has the standard Holzmann CFD bash script which explains the single steps needed to build the cyclic patches as well as the set-up of the appropriate boundary conditions. The case runs in two different modes. After meshing, the filling stage starts for a defined time. In mode two, the boundary conditions are changed, and the pressure drop is applied resulting in pumping the fluid up.

Holzmann CFD does not give any warranty to the numerical results that are obtained within this training case based on the fact that there is no verification or validation.
