AbstractIn this paper, we exploit a new series summation and convergence improvement technique (that is, Drazin and Tourigny [5]), in order to study the steady flow of a viscous incompressible fluid both in a porous pipe with moving walls and an exponentially diverging asymmetrical channel. The solutions are expanded into Taylor series with respect to the corresponding Reynolds number. Using the D-T method, the bifurcation and the internal flow separation studies are performed.

The article presents the results of using the COMSOL Multiphysics environment to perform one of the laboratory works of the Aerodynamics module of the Hydrogas and Aerodynamics discipline. In the COMSOL Multiphysics environment, it is proposed to simulate the process of a laminar flow of a viscous incompressible fluid around bodies of various geometric shapes, which allows you to visually visualize the boundary layer, its separation from the surface of the streamlined body.

The method of matched asymptotic expansions is used in the present paper to derive an approximate solution for transient flow of a viscous incompressible fluid in an annulus. The transient is caused by a sudden reduction of flow rate to zero. The laminar flow before deceleration can be either steady or unsteady but unidirectional. The solution is valid for short time intervals after sudden deceleration.

An analysis has been made of the characteristics of externally pressurized central recess conical bearings with nonconstant film thickness under the assumption of isothermal laminar flow of a viscous incompressible fluid. The flow in the narrow gaps that may be convergent, constant, or divergent has been approximately determined on the basis of the lubrication theory with convective inertia neglected except for that part which is due to rotation. The pressure distribution along the gap, the load capacity, and the torque of the bearings, were theoretically predicted. It was found that, while the gap is very narrow, both the load capacity and the torque for the convergent case decrease moderately, and for the divergent case increase significantly with respect to the constant gap bearing, provided with flow rate, rotational velocity and the film thickness at the outlet of the gap are the same.
