High temperature processes are used in a large variety of industrial application. Simulation helps to solve technological problems and increase energy efficiency in case of industrial scale simulation. We present in this paper a research equipment simulation. The aim is to increase knowledge of temperature field in the crystal growth region in order to give researcher some important information ...

A numerical simulation study, using COMSOL Multiphysics®, was carried out to examine the temperature and concentration fields in the dissolution process of silicon into germanium melt. This work utilized a simplified configuration which may be considered to be similar material configuration to that used in the Vertical Bridgman growth methods. The concentration profile for the SiGe sample ...

The increasing demand for improved metallurgical products strongly motivates the optimization of manufacturing processes and design of γ-TiAl products. Among the large variety of available forming processes, cold closed-die forging is particularly suitable for producing net shape bulk products having good surface finish with better mechanical properties. Pressing punches of suitable profile ...

In recent years lab-on-microchip technology has become a powerful tool for micro-scale analysis of biochemical processes. In the studied system the overall process consists of transport, convection, diffusion, reaction and adsorption processes. Two compounds A and B, contained in a carrier fluid (buffer), are introduced into a reaction channel via a Y-shaped double-inlet. As the streams flow ...

Heat transfer in a plane shear flow configuration consisting of two infinitely long parallel plates is considered. In laminar flows over undulated substrates eddies can be generated due to the kinematical constraints. A closed form analytical solution for the velocity field, based on lubrication theory as well as a semi-analytic solution for the temperature field is derived for the creeping flow. ...

In this paper we present a novel approach for modeling spatial distributed bio- chemical and environmental processes like the growth of plants and the related biochemical reactions. The physical phenomena like flow and mass transport can be described by fluid dynamics equations, but for effects like growth rates often no analytic models are available. However, in many cases experts have knowledge ...

We present a mechanical model a growing spherical shell suitable for predicting the evolution of a Saccular Cerebral Artery Aneurysms (SCAA). It relies basically on the Kröner-Lee decomposition, used to describe the interplay between the current and the relaxed configuration of body elements. Rupture or stabilization of a SCAA are the end effect of a number of biological mechanisms, still poorly ...
