Nonzero boundary condition for the unsteady micropolar pipe flow: well-posedness and asymptotics
In this paper, we consider the unsteady flow of a micropolar fluid through a thin pipe with the nonzero boundary condition for microrotation. We first prove the well-posedness of the corresponding initial-boundary ...

Mathematical results concerning unsteady flows of chemically reacting incompressible fluids
We investigate the mathematical properties of unsteady internal flows of chemically reacting incompressible fluids assuming Navier's slip boundary conditions on the impermeable boundary. We establish long-time and ...

Mathematical analysis of unsteady flows of fluids with pressure, shear-rate, and temperature dependent material moduli that slip at solid boundaries
We established an existence of suitable weak solution to unsteady flow of an incompressible fluid for a class of models where the material coefficient depend on the temperature, the shear rate and the pressure in 3D setting for Navier´s slip...

A SOLUTION OF UNSTEADY FLOW BY AN EXPANSION ON THE EIGEN SHAPES OF VELOCITY AND PRESSURE
Solution of the unsteady, laminar flow of the real compressible liquid by the method of Laplace transformation is presented in the paper. The resulting solution is as a function of the eigen shapes of velocity and pressure. It is assumed tha...

Modeling of the unsteady flow through a channel with an artificial outflow condition by the Navier-Stokes variational inequality
inequality of the Navier-Stokes type, simulating the unsteady flow of a viscous fluid through the channel, with the so-called 'do nothing' boundary condition on the outflow. The condition that the solution lies in...

Unsteady simulation of velocity and temperature field of the brake disc
Correct brake operation is a necessary condition for safe driving. During braking heat is generated, partly removed to the brake pads and partly removed to the brake disc. High temperature during braking and slowly outlet heat may cause: bra...
