Kinetic Effects in Spherical Expanding Flows of Binary-Gas Mixtures
Diffusion effects in the spherical expanding flows of argon-helium mixtures have been studied using the direct simulation Monte Carlo technique at the Knudsen numbers from 0.0015 to 0.03 and various pressure ratios. The similarity analysis was used to analyze the flow structure. Kinetic effects influence the shock-wave thickness, parallel and transverse species’ temperatures, diffusive velociti...
متن کاملOscillatory Marangoni convection in binary mixtures in square and nearly square containers
Three-dimensional simulations of oscillatory convection in binary mixtures driven by the Marangoni effect have been performed. The upper surface of the fluid is heated by a constant heat flux while the bottom is maintained at a constant temperature. Surface deflection is ignored. Oscillations are the result of concentration-induced changes in the surface tension due to the presence of an anomal...
متن کاملKinetic Phenomena in Spherical Expanding Flows of Binary Gas Mixtures
Diffusion and kinetic effects in the spherical expanding ows of argon–helium mixtures have been studied using the direct simulation Monte Carlo technique at the Knudsen numbers from 0.0015 to 0.03 and pressure ratios from 100 to 10,000. Similarity analysis was used to analyze the ow structure in supersonic ow region, spherical shock wave, and subsonic area behind it. Both kinetic and diff...
متن کاملLattice Boltzmann equation for microscale gas flows of binary mixtures.
Modeling and simulating gas flows in and around microdevices are a challenging task in both science and engineering. In practical applications, a gas is usually a mixture made of different components. In this paper we propose a lattice Boltzmann equation (LBE) model for microscale flows of a binary mixture based on a recently developed LBE model for continuum mixtures [P. Asinari and L.-S. Luo,...
متن کاملOscillatory convection in binary mixtures: thermodiffusion, solutal buoyancy, and advection.
The role of thermodiffusive generation of concentration fluctuations via the Soret effect, their contribution to the buoyancy forces that drive convection, the advective mixing effect of the latter, and the diffusive homogenisation are compared and elucidated for oscillatory convection. Numerically obtained solutions of the field equations in the form of spatially extended relaxed traveling wav...
