With increasing computer capabilities, numerical modeling of two-phase flows has developed significantly over the last few years. Although there are two main categories, namely 'one' fluid and 'two' fluid methods, the 'one' fluid methods are more commonly ...
We analyze the accuracy of wall shear stress measurements in lattice Boltzmann simulations that are based on a voxel representation of the geometry and staircase approximation of boundaries. Such approximations are commonly used in the context of lattice B ...
In the presented study Gd and the alloy Fe49Rh51 are considered to be possible magnetocaloric materials for a new hyperthermia method. From general principles of thermodynamics a new mathematical model allowing the calculation of heat transport in a tumor ...

This paper presents a theoretical and numerical model to predict film condensation heat transfer in mini and micro-channels of different internal shapes. The model is based on a finite volume formulation of the Navier-Stokes and energy equations and it inc ...
The two fluid model is used to simulate upward gas-liquid bubbly flow through a vertical conduit. Coalescence and breakup of bubbles have been accounted for by embedding the population balance technique in the two fluid model. The simulation enables one to ...
In a companion paper ("Modelling Bubbly Flow by population Balance Technique Part I: Axial Flow Development and Its Transitions, " ASME J. Fluids Eng), a two fluid model along with a multiclass population balance technique has been used to find out compreh ...
Large-Eddy Simulations (LES) of the turbulent compressible ow within heated curved ducts of square cross section are presented. The aim here is to predict the three- dimensional structures which develop inside cooling channels of rocket engines and study t ...
Two-phase flow of gases and liquids or vapors and liquids in pipes, channels, equipment, etc. is frequently encountered in industry and has been studied intensively for many years. The reliable prediction of pressure drop in two-phase flow is thereby an im ...
The current industrial need for compact high heat density cooling devices has conveyed an increasing interest on convective boiling in micro-channels. Although there is general agreement that these systems may be able to dissipate potentially very high hea ...
Cylindrical containers agitated by orbital shaking are being developed as simple and cost-effective bioreactor systems for the cultivation of mammalian cells. Here the oxygen transfer capacities of containers with nominal volumes from 50 mL to 2000 L were ...
