Metal hydrides are a widely-used method for storing and releasing hydrogen chemically under moderate conditions. This paper will present how highly dynamic metal hydride storage has been simulated and optimized using COMSOL Multiphysics. It will be shown how mass, energy and momentum ... 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
Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... Mehr lesen
Plasma torches are used in processing of materials and in energy industry for producing plasma. In this work we use the Equilibrium DC Discharge physics interface of COMSOL Multiphysics® to model a DC non- transferred arc plasma torch, under hypothesis of local thermodynamic equilibrium. ...

As a part of a lab-on-chip-device, more often it is required to measure dielectric constant of the fluid. For this purpose it is necessary to develop a sensor whose size is compatible with microfluidic channel. The work, presented in this paper, studies effect of the parameters ... Mehr lesen
This paper describes the design and characterization of an 8 slots resonant cavity Magnetron, which undergoes thermal-structural effects due to cathode heating. The proposed study involves Thermal Stress, Eigen-frequency and Particle Tracing analysis based on COMSOL Multiphysics®. ... Mehr lesen
The high speed gas turbine is a power plant developed for modern aircrafts. It is widely used and developed because it can meet the high power to weight ratio. The rotor system of modern small gas turbine works above the critical speeds. Hence, there is a stricter requirement for the ... Mehr lesen
One of the most important criteria for evaluating chemical enhanced oil recovery (EOR) processes that use polymers is its rheological behaviour which in turn account for other physical effects of adsorption and resistance factors during polymer-rock interactions. However, complete ... Mehr lesen
In the emerging field of MEMS microfluidics, micropumps and microvalves are two of the most important devices with a wide spectrum of applications such as programmable drug delivery systems, lab-on-a chip devices, µTAS (micro total analysis system), micro electric cooling applications ...
