[1] ETH Zürich, Zurich, Switzerland
[2] University of Applied Sciences, Dresden, Germany

Organogenesis, the genesis of organs during embryonic development, is an active research field involving biologists, mathematicians and computational researchers. Fundamental questions of the formation of shape and the control of growth are still not answered. We focus on the development ... 詳細を見る

Computational Fluid Dynamics Approach to Evaluate Electrostatic Precipitator Performance

M. Ahmadi [1]
[1] Faculty of Engineering Technology, University of Twente, Enschede, The Netherlands

Electrostatic precipitation is an extremely efficient way of filtering fine particles from the airstream. Electrostatic precipitators (ESPs) can control airborne emission without significantly slowing down the rate of flow, because of the low pressure drop across this type of filters. A ... 詳細を見る

[1]Centro Láser UPM, Universidad Politécnica de Madrid, Madrid, Spain

Laser-induced forward transfer (LIFT) is a non-contact direct-write technique that enables the deposition of small volumes of material into user-defined high-resolution patterns with a wide range of structural and functional materials. There are many variations of the LIFT process, each ... 詳細を見る

Comparison of Pipe Flow vs. CFD Module for Homogeneous Liquid Delivery to a Tank in a Cooling Reactor

L. Leis [1], D. Kray [1],
[1] Institute for Energy System Technology INES, University of Applied Sciences, Offenburg, Germany

We consider the fluid dynamics problem of homogeneously filling a large tank by multiple inlets fed from a piping system. Suitable pipe geometries must be chosen so that the volume flow is constant for all inlets. In this work, we compare both for a piping system as depicted in fig. 1: A ... 詳細を見る

Comparison Between COMSOL Multiphysics® and Star-CCM+® Simulation Results and Experimentally Determined Measured Data for a Venturi Tube

E. Weizel [1], A. Diring [1], L. Fromme [1], M. Petry [1]
[1] University of Applied Sciences, Department of Engineering Sciences and Mathematics, Bielefeld, Germany

Numerical simulation tools offer the opportunity to ascertain characteristic values, which are difficult to measure. A possible approach for validating simulation models by easy measurable data and gaining the needed values is described in this study of a Venturi tube. The examination of ... 詳細を見る

CFD Analysis of a Stirred Vessel Bioreactor with Double Pitch Blade and Rushton Type Impellers
