Separation Process by Porous Membranes: A Numerical Investigation

Numerical Investigation of Supersonic Nozzle Flow Separation

S EPARATION of supersonic flow in a convergent–divergent nozzle is a fundamental fluid phenomenon that affects a large variety of applications, from fuel systems to aircraft engine nozzles. When a supersonic nozzle is operated at pressure ratioswell below its design point, a shock forms inside the nozzle andflowdownstreamof the shock separates from the nozzle walls. Even though flow separation ...

Separation and Reaction Using Porous and Palladium Membranes

Porous Nanocomposites with Integrated Internal Domains: Application to Separation Membranes

Asymmetric membranes with layered structure have made significant achievements due to their balanced properties and multi-functionalities that come from a combination of multiple layers. However, issues such as delamination and substructure resistance are generated by the intrinsic layered structure. Here, we present a strategy to integrate the traditional layered structure into an asymmetric b...

Fabrication of SrCoo . SFeO , Oxygen Separation Membranes on Porous Supports

SrCoO.~FeO, (SCF) is an attractive material for oxygen separation membranes and for use in catalytic membrane reactors. While tubes of this material have been prepared by extrusion, further improvements in oxygen transport performance may be gained by preparing thinner membranes on porous supports. In this paper, we will discuss the deposition of thick films by spray deposition and centrifugal ...

A numerical investigation of phase change effects in porous materials

In this paper, a numerical study of heat and mass transfer with phase change in porous materials is performed. The problem is modelled by a system of transient inter-coupled equations governing the twodimensional multiphase transport process in porous media. The solution algorithm allows full simulation without any significant simplifications. The variations and the interrelationship between th...
