Analytical solutions are obtained for five basic viscoelastic fluid flow problems under harmonic fluctuating driving forces. Jeffrey's model is adopted in the study. The five fundamental problems are the fluctuating Couette flow, fluctuating wind-driven flow over finite and infinite fluid domains, ...
Hi, I'm having trouble solving just the most basic 2D fluid flow problems using time dependent studies. For example I want to look at flow through a simple pipe, and see what the flow is at 1 second, 2 seconds, 3 seconds, etc etc. Though the problem is they solve! I tried to use...
This first volume discusses fluid mechanical concepts and their applications to ideal and viscous processes. It describes the fundamental hydrostatics and hydrodynamics, and includes an almanac of flow problems for ideal fluids. The book presents numerous exact solutions of flows in simple configura.....
The traditional finite difference procedures are used in solving fluid flow problems. Different fluids show different relations between stress and the rate of deformation. Depending on the nature of relation followed between stress and rate of deformation, fluids can be classified as Newtonian and non...

We extend earlier work in this direction to solve incompressible fluid flow problems governed by the steady Stokes equations. Particular focus is given to satisfying the inf-sup condition, to a posteriori error estimation, and to "gluing" the local solutions together in the multidomain case. 展开...
In the placental villi, nearly the entire maternofetal and fetomaternal exchange takes place. There is only a limited contribution to this exchange by the extraplacental membranes. In addition, most metabolic and endocrine activities of the placenta have been localized in the villi (for review, ...
aThe purpose of this essay was the direct numerical simulation of heat and fluid flow by granular mixing in a horizontal rotating kiln. To model particle behaviour and the heat and fluid flow in the drum, we solve the mass conservation, momentum and energy conservation equations directly on a ...
