HIGH ORDER
THERMAL CREEP EFFECTS IN ISOTHERMAL WALL MICROCHANNELS
In the present work the effects of thermal creep on
the development of fluid flow and heat transfer in
rectangular microchannels with constant wall
temperature in the slip flow regime, 10-3 ≤ Kn ≤ 10-1, is...
Effects of thermal creep and high order slip/jump on natural convection in microchannels
Natural convection gaseous slip flows in open-ended vertical parallel-plate microchannels with symmetric wall heat fluxes are numerically investigated. A second-order model, including thermal creep effects, is considered for velocity slip...
Slip-flow and heat transfer in rectangular microchannels in the presence of thermal creep
بررسی عددی جریان سیال و انتقال حرارت سه بعدی در ناحیه ورودی یک ریزمجرای مستطیلی
A control-volume numerical approach has been used to study rarefaction effects in simultaneously hydrodynamically and thermally developing 3D micro flows in rectangular channels for Kn ≤ 0.1. The effects of velocity slip, thermal creep...
Numerical investigation of Knudsen pump performance
It is well known that in a gas-filled duct or channel along which a temperature gradient is applied, a thermal creep flow is created. The performance of a new type of Knudsen pump, which only requires
isothermal hot or cold walls...
Heat transfer in open microchannel at constant heat flux
-Kutta and shooting method. Consequently, the velocity profiles, the temperature profiles, the wall shear stress and the local Nusselt number exhibit a dependence on the slip coefficient. The results illustrate that the thermal creep term has a very small effect...
Heat Transfer and Fluid Characteristics of Rarefied flow in Thermal Cavities
In the present study, we investigate the characteristics of thermal cavity/ in the rarefied flow
regime using direct simulation Monte Carlo (DSMC). We use a recently developed iterative technique
to impose a ...
Effects of High-Order Slip/Jump, Thermal Creep, and Variable Thermophysical Properties on Natural Convection in Microchannels With Constant Wall Heat Fluxes
Natural convection gaseous slip flows in open-ended vertical parallel-plate microchannels with symmetric wall heat fluxes are numerically investigated. A second-order model, including thermal creep effects, is considered for velocity slip...
Mass flow rate prediction of temperature-driven gas flows through divergence micro/nanochannels
numbers. However, the mass flow rate increases with the
divergence angle when Knudsen number is high. We show
that enhanced thermal creep effect is the main source of the
mass flow rate increase if the wall temperature gradient is
increased....
Slip-Flow and Heat Transfer in Isoflux Rectangular Microchannels with Thermal Creep Effects
-flow
regime (10-3 ≤ Kn ≤ 10-1). The effects of velocity slip and thermal creep on the key flow parameters are examined in
detail. Low Reynolds number flows (Re ≤ 1) for different channel aspect ratios (0 ≤ α* ≤ 1) are considered. The...
