Abstract
Hydrodynamics of viscous fluids deals with Navier-Stokes equation - a partial differential equation with unknown distributions for velocity and pressure in a flow domain. It is difficult to find its analytical solution, especially in cases of unsteady flows, flows of non-Newtonian or rheomagnetic fluids. It is usually solved numerically using finite difference, finite element, or control volume methods. The goal of this research is application of proposed physics-based loss to rheomagnetic fluids flows modeling. The basic network architecture is U-Net. The network receives an image of the flow domain and calculates the fluid velocity distribution in a form of an image of the stream function distribution. The network was tested for the asymptotic case, the results were compared with numerical solution and known analytical solution. Proposed tool allows modeling 2D flows of rheomagnetic fluids. The proposed method is general and allows modeling 3D flows.
