The influence of fluids inertia and the effects of the presence of a magnetic field normal to the direction of the flow of an electrically conducting fluid are studied on flow and heat transfer inside a nonisothermal and incompressible thin film undergoing oscillatory squeezing. The governing equations have been nondimensionalized and solved numerically. Further, the influence of the squeezing ...

a subsurface drainage network mainly carries unsteady flow and data are not usually available for model parameters calibration in such networks. in the present research, the finite volume method using the time splitting scheme was employed to develop a computer code for solving the one dimensional unsteady flow equations. using corrugated sub drainage pipes, an experimental prototype setup was ...

The process of water treatment by nanoparticles is one the most considerable subjects in cross-field hydrodynamics, chemistry, and mathematics. This paper dedicated to case flows that appear when squeezing stretching a channel with mixing water, nanoparticles, contaminants. It assumed fluid homogeneous at starting moment, parameters contaminants are known, there constant non-homogeneous magneti...
