Fusion weld metal solidification:Continuum from weld interface to centerline
(Lappeenranta University of Technology, 2008-03-07)
We present a brief résumé of the history of solidification research and key factors affecting the solidification of fusion welds. There is a general agreement of the basic solidification theory, albeit differing - even ...
Ion-exchange resins as stationary phase in reactive chromatography
(2005)
Dynamic behavior of bothisothermal and non-isothermal single-column chromatographic reactors with an ion-exchange resin as the stationary phase was investigated. The reactor performance was interpreted by using results ...
Particle transport method for convection-diffusion-reaction problems
(2007-12-01)
Convective transport, both pure and combined with diffusion and reaction, can be observed in a wide range of physical and industrial applications, such as heat and mass transfer, crystal growth or biomechanics. The numerical ...
Modeling of non-isothermalvapor membrane separation with thermodynamic models and generalized mass transfer equations
(2002-05-30)
A rigorous unit operation model is developed for vapor membrane separation. The new model is able to describe temperature, pressure, and concentration dependent permeation as wellreal fluid effects in vapor and gas separation ...
