Week Two

There has been previous work on oil jet cooling at Oakland University. Graduate student Gary Liu has wrote a complete dissertation on his experimental data of oil jet cooling experiments. Another graduate student, Bolong "Polo" Ma replicated some of Gary's experimental data through CFD simulations. We will be continuing to verify some of these experiments as well as generate new data of our own. This week, we met with Polo to gain a better understanding of his abstract mesh that was used in the simulation. The mesh was highly refined in some areas that needed to be coarsened. In order to adjust these portions of the mesh, a replication of the model needed to be made in the meshing software, ICEM CFD. This new mesh will be used for future simulations However, there were technical issues that hindered our progress in doing so. In order to solve the problem, there needed to be a better understanding of the mesh designer tools, so this week also consisted of working through a few meshing tutorials. The two simulations that needed to be continued began running well. However, there were issues getting the newer simulations running; some of the calculated variables diverged very early. We are still currently looking into solving this issue.
