On the Kinetic Equations for Binary Mixtures

Kinetic Theory for Binary Granular Mixtures at Low-Density

Many features of granular media can be modelled as a fluid of hard spheres with inelastic collisions. Under rapid flow conditions, the macroscopic behavior of grains can be described through hydrodynamic equations. At lowdensity, a fundamental basis for the derivation of the hydrodynamic equations and explicit expressions for the transport coefficients appearing in them is provided by the Boltz...

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...

Kinetic 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...

global results on some nonlinear partial differential equations for direct and inverse problems

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
