COOLING IN CONSTANT WALL TEMPERATURE MICROCHANNELS WITH THERMAL CREEP EFFECTS
Fluid flow and heat transfer in the entrance region of
rectangular microchannels of various aspect ratios, 0.2 ≤ α* ≤ 1,
are numerically investigated in the slip flow regime, 10-3 ≤ Kn

Numerical simulation of slip flow over flat plate
. In this study a Computational Fluid Dynamic (CFD) method with slip velocity boundary condition is employed to solve the laminar slip flow over flat plate. In this investigation the effects of slip boundary condition on skin friction, velocity profile, boundary...
Slip-Flow Heat Transfer in Trapezoidal Microchannels
A numerical study of simultaneously developing velocity and temperature fields in trapezoidal microchannels has been conducted in the slip-flow regime. A control-volume based numerical method is used to solve the Navier-Stokes and energy equations...
Low Mach number slip flow through diverging microchannel
This paper presents experimental and three-dimensional numerical study of gaseous slip flow through diverging microchannel. The measurements are performed for nitrogen gas flowing through microchannel with different divergence angles (4°, 8°, 12...
Heat transfer characteristics of slip flow over solid spheres
In this study, heat transfer characteristics of slip flow over an isolated impermeable solid sphere are investigated numerically. An isothermal solid sphere is considered at intermediate Reynolds numbers (04Re450) for Prandtl numbers in the range...
Heat transfer in open microchannel at constant heat flux
on the solution. It is shown that laminar boundary layer of gas fluid with slip flow tends to increase near wall fluid axial velocity and temperature jump on the wall as the flow becomes more rarefied. It will be seen that heat transfer in open microchannels...
Pressure-driven electrokinetic slip-flow in planar microchannels
This paper presents an analytical solution for pressure-driven electrokinetic flows in planar microchannels
with velocity slip at the walls. The Naviere Stokes equations for an incompressible viscous fluid
have ...
Slip-Flow and Heat Transfer in Isoflux Rectangular Microchannels with Thermal Creep Effects
A control-volume numerical approach has been used to study rarefaction effects in simultaneously hydrodynamically
