Investigating the Effects of Mass Transfer and Mixture Non-Ideality on Multiphase Flow Hydrodynamics Using CFD Methods
A numerical framework has been proposed to model the interacting effects of mixture non-ideality and mass transfer on hydrodynamics of a multiphase system using CFD methods.Mass transfer during condensation and vaporization is modeled by chemical potential at the liquid-vapor interface. Species mass transfers are related to the diffusion at the interface which in turn is related to the conc...
متن کاملSynthesis of HA nanoparticles in the presence of anionic and cationic polyelectrolyte
Nanosized hydroxyapatite (HA) powders have been synthesized by an inverse microemulsion system using cyclohexane, an anionic surfactant and aqueous solutions of calcium nitrate tetrahydrate and biammonium hydrogen phosphate in the presence of anionic and caionic polyelectrolyte with the inducement of ultrasound irradiation. Prepared HA in presence of anionic polyelectrolyte has a different morp...
متن کاملNon- Ideality and Ion-Pairing in Saturated Aqueous Solution of Lithium Carbonate at 25°C
Using Solvent Evaporating and Atomic Emission Spectrophotometric methods, the solubility of Li2CO3 in waterat 25°C was determined. Comparing the value of thermodynamic solubility product constant, Ksp(th),(Ksp(tn) = exp(—AG.ss/RT)) of the mentioned salt to the value which is obtained from the observed solubility,shnolL-1 , and activity coefficients, f+ and f, which are estimated upon the extend...
متن کاملParaffin crystallization in synthetic mixtures: Predictive local composition models revisited
Aiming at identify the shortcomings of the available models for the description of the solid phase non-ideality, new solid liquid equilibrium data for multicomponent hydrocarbon systems was measured. The Predictive UNIQUAC and Wilson models for the description of the solid p d s m ©
متن کاملThe Maxwell-Stefan diffusion limit for a kinetic model of mixtures
We consider the non-reactive elastic Boltzmann equation for multicomponent gaseous mixtures. We deduce, under the standard diffusive scaling, that well prepared initial conditions lead to solutions satisfying the Maxwell-Stefan diffusion equations in the vanishing Mach and Knudsen numbers limit.
