Pseudospectral Solutions for Steady Motion of a Viscous Fluid Inside a Circular Boundary
نویسنده
چکیده
Numerical solutions are presented for steady two-dimensional motion within a circular cylinder generated by uid injecting radially over one small arc and ejecting radially over another arc. These solutions are based on a mixed nite-diierence pseudospectral method. Previous calculations were able to obtain convergent results only for a range of Reynolds numbers from R = 0 to R = 20. The main object of this study is to extend the Reynolds number range for reliable solution, particularly with regard to the ow patterns, based on a pseudospectral approach.

Effect of time dependent normal transpiration on the problem of unsteady viscous flow and heat transfer in the vicinity of an axisymmetric stagnation point of an infinite circular cylinder moving simultaneously with time-depended angular and axial velocities and with time-dependent wall temperature or wall heat flux are investigated. The impinging free stream is steady with a strain rate . A re...

In this paper, we study the effects of Hall and ion-slip currents on the steady magneto-micropolar of a viscous incompressible and electrically conducting fluid over a horizontal plate by taking in to account the viscous dissipation effects. By means of similarity solutions, deviation of fundamental equations on the assumption of small magnetic Reynolds number are solved numerically by using qu...

متن کاملUnsteady Motions of a Maxwell Fluid Due to Longitudinal and Torsional Oscillations of an Infinite Circular Cylinder
Flows in the neighborhood of spinning or oscillating bodies are of interest to both academic workers and industry. Among them, the flows between oscillating cylinders are some of the most important and interesting problems of motion near oscillating bodies. As early as 1886, Stokes [1] established an exact solution for the rotational oscillations of an infinite rod immersed in a classical linea...

We studied the growth of viscous fingers as a Laplacian growth by conformal mapping. Viscous fingers grow due to Saffman-Taylor instability in the interface between two fluids, when a less viscous fluid pushes a more viscous fluid. As there was an interest in the rectangular Hele-Shaw cell, we solved the Laplacian equation with appropriate boundary conditions by means of conformal mapping tech...
