An effect of periodic temperature and concentration on unsteady free convective, viscous incompressible flow and heat transfer in slip-flow regime is carried out. Assuming variable suction at the plate, approximate solutions ...

Time dependent flow of an Oldroyd liquid B in a straight circular tube is examined. An approach to describe the flow when a general pressure-gradient and general initial conditions are given, is considered. The initial ...

The problem of unsteady three-dimensional flow of an incompressible viscous fluid between two horizontal parallel porous plates with transverse sinusoidal injection of the fluid at the stationary plate and with constant ...

We present a numerical scheme for a previously unexploited formulation of the equations for unsteady viscoelastic flow. The formulation aligns the polymer stress along particle paths/streamlines, utilising the characteristic ...

Numerical modeling of pile scour is performed due to the action of unsteady currents and oscillatory flow greens, using 3D Reynolds averaged Navier-Stokes (RANS) equations for the hydrodynamic description and the Exner ...

A range of quasi-steady and unsteady aerodynamic models are used to predict the aerodynamic forces experienced by a flapping wing and a detailed comparison amongst these predictions in provided. The complexity of the models ...

The transient process of solidification of laminar liquid flow (water) submitted to super-cooling was investigated both theoretically and experimentally. In this study an alternative analytical formulation and numerical ...

Blood flow dynamics play an important role in the pathogenesis and treatment of intracranial aneurysms. The evaluation of the velocity field in the aneurysm dome and neck is important for the correct placement of endovascular ...
