Eugeny Varseev, username @varsey in the SimScale community, graduated from Obninsk Institute for Physics and Power Engineering (Obninsk, Russia) where he majored in Nuclear Reactors Research and Design. He is currently doing his Ph.D. research on heat exchanger simulation and optimization.
We interviewed him and talked about how the SimScale community is helping him with his research.
Eugeny: I found out about SimScale in a CFD group on LinkedIn. I tried to use it last summer, but it seemed to be too difficult for me at that time. Later, I successfully started again with the help of tutorial videos and workshops for beginners. Since then I have been actively using SimScale.
Eugeny: Recently, I have finished a heat exchanger simulation with a filter element. It is basically a big cylinder with an inlet tube inserted into it and outlet tube at the top. The filter element is located in the upper part of the heat exchanger. The flow inside the domain is being cooled down from the outside. The main difficulty in this heat exchanger simulation for me was taking into account the strong buoyancy effects which create a downstream flow near the walls of the domain, while the main flow goes up. Another difficult part was creating a robust mesh, but the SimScale interface allows creating several meshes within one project, and this made it easier.
Eugeny: I am really satisfied with the results that I’ve gotten. In this regard, I should mention that SimScale has a nice option built in to control results by tracking the values of different fields while a computation is running. It’s a bit tricky to implement such a thing on your local PC.
Eugeny: Thank you so much! My main motivation was to perform a simple simulation of forced convection buoyant flow as a SimScale example case since there was just one case of this kind and it was pretty sophisticated. The post-processing was a bit tricky, but apart from that, there were no problems.
Eugeny: I love how SimScale lets me manage my projects—I have all my geometries, meshes, simulation runs, and even post-processing in one project. I also get to use it from any local PC available to me at the moment. Also, the automatic meshing with the snappy hex mesher is pretty nice. Controlling results on the go, as I mentioned, is quite good as well.
Eugeny: I am looking for more turbulence models and numerical schemes to be available in the case setup. It also would be nice to have a Surface mode in the viewer set up by default, since it takes a lot of time and resources to load a case with a relatively big mesh on a slow PC. Finally, it would be great to have a results control feature for uploaded OpenFOAM cases (when they have necessary configuration files in them, of course).
Eugeny: I am planning to work with two-phase flow simulations. It takes a lot of long runs with different setups, so SimScale would be very helpful to me. Even though SimScale doesn’t support the two-Phase-Euler-Foam solver natively, I will be able to continue the simulation by uploading OpenFOAM cases.
