Modeling and Simulation of the interaction between oil and rotating gear within Final drive volume

An adaptive mesh refinement (AMR) method based on discretization matrix metric is described. The computational algorithm is implemented using OpenFOAM parallel library. This open C++ library provides data structures and routines to work with the finite volume method and adaptive mesh. The method was used for oil flow in final drive simulation. For more efficient use of computing resources, we decided to use an approach based on the use of adaptive mesh refinement/coarsening. Adaptive mesh refinement approach showed greater efficiency in cases of low rotational frequencies and less efficiency in case of high frequency.
