Phase Change Simulation for Isothermal Compressible Two-Phase Flows

On a non-isothermal diffuse interface model for two-phase flows of incompressible fluids

We introduce a diffuse interface model describing the evolution of a mixture of two different viscous incompressible fluids of equal density. The main novelty of the present contribution consists in the fact that the effects of temperature on the flow are taken into account. In the mathematical model, the evolution of the velocity u is ruled by the Navier-Stokes system with temperaturedependent...

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

On the mesoscopic Eulerian formalism for the simulation of non-isothermal dilute turbulent two-phase flows

We address the numerical simulation of particle-laden turbulent flows in the dilute regime, i.e., when the volume fraction of the dispersed phase is small. However, because of the potentially large density difference between the two phases, the dispersed phase may be significantly inertial and not exactly follow the carrier. For a dilute two-phase flow (typically a cloud of droplets or solid pa...

The Drift-flux Asymptotic Limit of Barotropic Two-phase Two-pressure Models

We study the asymptotic behavior of the solutions of barotropic two-phase twopressure models, with pressure relaxation, drag force and external forces. Using Chapman-Enskog expansions close to the expected equilibrium, a drift-flux model with a Darcy type closure law is obtained. Besides, restricting this closure law to permanent flows (defined as steady flows in some Lagrangian frame), we can ...
