Abstract:
A regularization of two types and aggregation are performed for the system of equations of motion for a multivelocity mixture of viscous incompressible fluids, and new multivelocity and single-velocity systems are constructed. For all of them, elliptic equations for the pressure and dissipative balance equations for the total energy of the mixture (the sum of its kinetic and potential energies) are derived.
Keywords:
equations of motion for a mixture of viscous incompressible fluids, regularization, aggregation, pressure equation, total energy balance equation.
