Thermal creep of a rarefied gas on the basis of non-linear Korteweg-theory
The study of thermal transpiration or more commonly called thermal creep is accomplished by use of Korteweg’s theory of capillarity. Incorporation of this theory into the balance laws of continuum mechanics allows resolution of boundary value problems via solutions to systems of ordinary differential equations.
متن کاملThermal Loading of a Direct Drive Target in Rarefied Gas
In an inertial fusion energy (IFE) power plant, each fusion micro-explosion (~10 Hz) causes thermal and structural loads on the IFE reactor wall and driver optics. The loading on the wall must remain sufficiently low to ensure that economic and safety constraints are met. One proposed method for decreasing the intensity of the wall loading is to fill the reaction chamber with a gas, such as Xe,...
متن کاملPoiseuille and Thermal-Creep Flowin a Cylindrical Tube
A version of the discrete-ordinates method is used to solve, for the case of flow in a cylindrical tube, the classical Poiseuille and thermal-creep problems based on the Bhatnagar, Gross, and Krook model in the theory of rarefied-gas dynamics. In addition to the development of a discrete-ordinates solution that is valid for a wide range of the Knudsen number, the solution is evaluated numerical...
متن کاملNumerical Simulations of Rarefied Gases in Curved Channels: Thermal Creep, Circulating Flow, and Pumping Effect
We present numerical simulations of a new system of micro-pump based on the thermal creep effect described by the kinetic theory of gases. This device is made of a simple smooth and curved channel along which is applied a periodic temperature field. Using the Boltzmann-BGK model as the governing equation for the gas flow, we develop a new numerical method based on a deterministic finite volume ...
متن کاملGas flow driven by thermal creep in dusty plasma.
Thermal creep flow (TCF) is a flow of gas driven by a temperature gradient along a solid boundary. Here, TCF is demonstrated experimentally in a dusty plasma. Stripes on a glass box are heated by laser beam absorption, leading to both TCF and a thermophoretic force. The design of the experiment allows isolating the effect of TCF. A stirring motion of the dust particle suspension is observed. By...
