With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research ... En savoir plus

The design of modern electric insulation devices for medium and high voltage (HV) applications requires computational work that goes beyond solving just a Laplace equation for the electric potential, and limiting the electric field below critical values. Both field calculation and ... En savoir plus

Museum buildings strive for a stable indoor climate to reduce the risk of cultural object degradation. An incorrect temperature or relative humidity can induce or accelerate deterioration processes such as biological, chemical or mechanical degradation. In order to reduce these risks, ...

The current work is aimed to simulate the production of high quality fatty acid methyl ester (biodiesel) production from palm oil in a micro porous ceramic membrane reactor. The TiO2/Al2O3 ceramic membrane was used as the separator and catalytic bed. It was packed with potassium ... En savoir plus

The pore sizes of many membranes being studied for separating the components in gas mixtures are on the scale of nanometers. Depending on the specific gases and pressures being used, this scale will put the flows in the Transition between Slip Flow and Knudsen regime. The differential ... En savoir plus

Indoor ventilation with good air quality control prevents infection with minimizing the spread of airborne respiratory and other infections in hospitals. CFD can be utilized to optimize flow pattern in clean rooms especially hospital clean rooms. More than two million people in Europe ... En savoir plus

The advent of Micro/Nano fluidic technologies has enabled researchers from various fields to use these advancements for analysis and experiments. In this work we present such a device that can be used for analyzing coagulation of blood in a microchannel by measuring the displacement of ... En savoir plus

Introduction In this study, we investigate the damping mechanisms of particle resonances in acoustofluidic systems using the finite element framework of COMSOLTM. In the field of acoustic micro-manipulation, pressure waves are used for the contactless handling of micro-meter sized ... En savoir plus

We propose a simplified numerical method to model the flow field downstream of an axial impeller. The method can be used for any axial hydraulic machinery for which, one is less interested by the flow between the blades, than by the flow field downstream of the machinery. The method is ...

Surface acoustic wave (SAW) devices are commonly used as wireless filters, resonators, and sensors. The confinement of acoustic energy near the surface of a piezoelectric substrate in a SAW sensor makes it highly sensitive for discerning surface perturbation. As sensors, SAW devices have ...
