Mixed and Forced Convection of Viscoelastic Materials in Straight Duct with Rectangular Cross Section
Fluid flow and heat transfer of viscoelastic materials in noncircular duct are complicated subject because of nonlinear behavior of rheological properties. In this paper flow and heat transfer of CEF fluids are studied with numerical modeling. Numerical solution is based on the artificial compressibility method and by using staggered mesh. The effect of secondary flows on the forced and natural...
متن کاملPULSATILE MOTION OF BLOOD IN A CIRCULAR TUBE OF VARYING CROSS-SECTION WITH SLIP FLOW
Pulsatile motion of blood in a circular tube of varying cross-section has been developed by considering slip flow at the tube wall and the blood to be a non- Newtonian biviscous incompressible fluid. The tube wall is supposed to be permeable and the fluid exchange across the wall is accounted for by prescribing the normal velocity of the fluid at the tube wall. The tangential velocity of the fl...
متن کاملSlip-flow Pressure Drop in Microchannels of General Cross-section
In the present study, a compact analytical model is developed to determine the pressure drop of fully-developed, incompressible, and constant properties slip-flow through arbitrary cross-section microchannels. An averaged firstorder Maxwell slip boundary condition is considered. Introducing a relative velocity, the difference between the bulk flow and the boundary velocities, the axial momentum...
متن کاملFlow in Slowly Varying Microchannels of Rectangular Cross-section
Copyright ©2009 by ASME ABSTRACT Laminar fully developed flow in streamwise-periodic microchannels of rectangular cross-section has been studied in this work. Based on the lubrication approximation, an analytical approach is proposed for the frictional flow resistance. Using the analytical model developed for straight channels of arbitrary cross-section, compact models are developed for linear ...
متن کاملThree Dimensional Laminar Convection Flow of Radiating Gas over a Backward Facing Step in a Duct
In this study, three-dimensional simulations are presented for laminar forced convection flow of a radiating gas over a backward-facing step in rectangular duct. The fluid is treated as a gray, absorbing, emitting and scattering medium. The three-dimensional Cartesian coordinate system is used to solve the governing equations which are conservations of mass, momentum and energy. These equations...
