Unsteady boundary layer flow of a Casson fluid past a wedge with wall slip velocity
In this paper an analysis is presented to understand the effect of non–Newtonian rheology, velocity slip at the boundary, thermal radiation, heat absorption/generation and first order chemical reaction on unsteady MHD mixed convective heat and mass transfer of Casson fluid past a wedge in the presence of a transverse magnetic field with variable electrical conductivity. The partial differential...
متن کاملThermocapillary Flow Near a Cold Wall
The thermocapillary feedback mechanism important at the edge of weld pools and other materials processes is examined through a model problem A pool of liquid with a at horizontal free surface is bounded on one side by a vertical solid wall which is maintained at a cold temperature to unit depth and at a warmer temperature below far away the uid is at the warmer temperature Surface tension is a ...
متن کاملNumerical Study of Reynolds Number Effects on Flow over a Wall-Mounted Cube in a Channel Using LES
Turbulent flow over wall-mounted cube in a channel was investigated numerically using Large Eddy Simulation. The Selective Structure Function model was used to determine eddy viscosity that appeared in the subgrid scale stress terms in momentum equations. Studies were carried out for the flows with Reynolds number ranging from 1000 to 40000. To evaluate the computational results, data was compa...
متن کاملEffect of surface slip on Stokes flow past a spherical particle in infinite fluid and near a plane wall
The motion of a spherical particle in infinite linear flow and near a plane wall, subject to the slip boundary condition on both the particle surface and the wall, is studied in the limit of zero Reynolds number. In the case of infinite flow, an exact solution is derived using the singularity representation, and analytical expressions for the force, torque, and stresslet are derived in terms of...
متن کاملNear-body flow dynamics in swimming fish
We consider the motions and associated flow patterns of a swimming giant danio (Danio malabaricus). Experimental flow-visualization techniques have been employed to obtain the unsteady two-dimensional velocity fields around the straight-line swimming motions and a 60 degrees turn of the fish in the centerline plane of the fish depth. A three-dimensional numerical method is also employed to pred...
