Numerical analysis of free surface flow using blue CFD

First, how to use the interFoam solver, which is capable of free surface analysis, was investigated for an analysis problem of a general small boat moving on a wave-rough water surface. It was found that it is necessary to make the free surface above and below the sea surface dense and generate a cubic grid. Next, we applied this solver to the flow around an automobile tire housing. In snowy and cold regions, the formation of ice blocks on tire housings in winter is a problem, and we are currently researching the suppression of ice block formation using plasma actuators (PA). We confirmed that analysis using interFoam can effectively simulate the visualization results of the flow around a rotating tire. We will use it to identify problems in wind tunnel models and to consider the position of PA electrodes.
