Excessive air damping can be detrimental to the performance of oscillating MEMS components. Complex systems, such as structures in pre-etched cavities or angular comb-drive scanning mirrors, typically require simulations to reliably evaluate the air damping. The simulated and ... Mehr lesen
Intense research has been carried out into methods that aim at harvesting fetal cells from maternal blood as substitutes to amniocentesis and chorionic villus sampling. This work focuses on the separation of fetal nucleated red blood cells from the maternal circulation based on their ... Mehr lesen
In this contribution we present the results of the numerical modeling and performance optimization study of a diaphragm pump for drug infusion. The main objective is to develop a numerical model that replicates the pumping cycle (400ms) and also provides indications about the variation ... Mehr lesen
Designing and constructing a lab-on-a-chip device poses a variety of questions. Transport of all required substances, detection of the analyte and its deposition on a sensor have to be incorporated. Different strategies have been developed to achieve good coverages of the sensor, like ... Mehr lesen
COMSOL Multiphysics® is used to simulate a thermal transport based flow sensor, which will be embedded in a micro-channel of a Poly-methyl methacrylate (PMMA) based microfluidic device. The channel height is 100μm and for simulation purposes the lengths has been set to 1.2mm. The heater ... Mehr lesen
This paper describes the Virtual Prototype of a Dielectric Window or High Power Microwave Vacuum Tubes and Linear Accelerators. Design formulas are provided and Computer Aided Design techniques based on COMSOL Multiphysics® software are proposed. The virtual prototype considers the ... Mehr lesen
The ceramic metal halide lamps belong to the most efficient high intensity light sources of these days. Presently it is the nitrogen contamination that causes the most significant problems during ignition. If this material gets into the lamp's interior in high concentrations, it will ... Mehr lesen
Comprehensive studies of drug transport in nanofibres based mats have been performed to predict drug release kinetics. The paper presents our approach to analyze the impact of fibers arrangement, one of the parameters varied in our parallel experimental studies. COMSOL Multiphysics® has ... Mehr lesen
Metal foams are interesting materials with many potential applications. They are characterized by a cellular structure represented by a metal or metal alloy and gas voids inside (Fig.1). A common metallic cellular material is aluminum foam which can be produced metallurgically by heating ... Mehr lesen
The core of this modelling is to study heat transfer and fluid dynamics processes for a compression expansion system, and the main particularity is that heat transfer and air movement are due to the movement of the piston. We have implemented a \"moving mesh\" solver to compute the ... Mehr lesen
