Hopf Bifurcation of the Unsteady Regularized Driven Cavity Flow
A numerical simulation of the unsteady incompressible flow in the unit cavity is performed by using a Chebyshev-Tau approximation for the space variables. The high accuracy of the spectral methods and the condensed distribution of the Chebyshev-collocation points near the boundary enable us to obtain reliable results for high Reynolds numbers with a moderate number of modes. It is found that th...
متن کاملtwo dimensional mathematical model of unsteady flow in lakes and estuaries using symmetrical grid
in this study, a method which is based on the integration of navier-stokes and continuity equations has been used to develop the governing equations. in these equations the coriolis acceleration and the effect of wind also have been considered. the main application of the model is to solve two dimensional problems with free surface in the plane. the offshore engineering projects and the hydrody...
متن کاملUnsteady Numerical Investigations of Flow and Heat Transfer Characteristics of Nanofluids in a Confined Jet Using Two-Phase Mixture Model
The development of high-performance thermal systems has increased interest in heat transfer enhancement techniques. The application of additives to heat transfer liquids is one of the noticeable effort to enhance heat transfer. In this paper two-dimensional unsteady incompressible nanofluid flow in a confined jet at the laminar flow regime is numerically investigated. The Mixture model is consi...
متن کاملnumerical solution of unsteady two dimensional couette flow, using finite difference lbm
a two dimensional finite difference lattice boltzmann method (fdlbm) for computing single phase flow problems is developed here. temporal term is discretized with low dissipation-low dispersion. discretization of convective term is implemented with third order upwind method. it will be explained governing equations and numerical method. methodology of imposing boundary conditions in fdlbm is de...
متن کاملMathematical Modeling of Two-dimensional Unsteady Flow in Growing Tumor
We investigate the problem of unsteady fluid flow in growing solid tumors. We develop a mathematical model for a growing tumor whose boundary is taken as a sphere, and the unsteady fluid flow within the tumor is assumed to be two dimensional with respect to the radial distance and the latitudinal angle in spherical coordinates. The expressions for the time, radial and latitudinal variations of ...
