A synthetic Jet actuator is a device which moves a fluid in and outside a cavity, through a small aperture, by the continuous oscillation of a diaphragm. The multiphysics interaction between the piezoelectric disk, which deforms due to the alternating voltage, and the fluid makes COMSOL ... 詳細を見る
A discrete model for the prediction of relative ion bombardment flux and target erosion in planar sputtering magnetrons is implemented in COMSOL Multiphysics®. Planar magnetrons are used within physical vapor deposition (PVD) processes to form thin film depositions on various types of ... 詳細を見る
This study highlights the possibility of using COMSOL Multiphysics for solving large scale PEM fuel cell stack models in the order of several million degrees of freedom (DOF). First, different gas flow channel configurations are solved in order to highlight the fluid flow and pressure ... 詳細を見る
In a nuclear reactor, the containment is the last barrier for the release of radioactivity during severe accident conditions. Containment material can be concrete or steel or steel-lined concrete. Steel containments have a high load bearing capacity and a high degree of leak tightness at ... 詳細を見る
In 1901 Weiss proposed an equation predicting activation of nerve fibers by electrical stimulation, used in neuroscience and neuromodulation, which applies electric fields to modify nerve behavior in neurological disorders. Weiss’ equation is relative to geometry, electrode array, ... 詳細を見る
This paper investigates the evolution of a single bubble going through growth, pinch-off, and condensation while rising due to buoyancy forces in a sub-cooled liquid. Phase change is modeled on the evolving liquid-vapor interface by considering changes in enthalpy and heat fluxes at the ... 詳細を見る
2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The ... 詳細を見る
In previous works a dissipative hydrodynamic model was used to simulate the behavior of a dense granular solid flowing through silos with simple geometries or with internal devices, showing good agreement with experimental results. That model has been upgraded taking into account the ... 詳細を見る
In this paper, we present the numerical modelling of a free-burning arc and its application to the understanding of optical mirage effect which could occur in a TIG (Tungsten Inert Gas) device used in welding applications. 詳細を見る
Enzyme reactions, blood flow and diffusion in human vasculature play interacting and fundamental roles in blood coagulation. In this complex mechanism, the balance between blood and clot is a delicate equilibrium, whose tight regulation is vital to avoid pathologies such as bleeding and ... 詳細を見る
