This presentation summarizes three different types of modeling using COMSOL Multiphysics. It is divided into three parts: Compressible flow, Multiphase flow, and Plasma Simulations. For the first part, we perform a special case study of the Mass Flow Verifier. A Mass Flow Verifier validates...

In this paper, we discuss simulation of one-port Surface Acoustic Wave (SAW) resonators using COMSOL Multiphysics. Resonator action can be achieved in one of the two ways; a single Inter-digital Transducer (IDT) having several fingers over a piezoelectric substrate or a short IDT with...

In this paper, a numerical model for time-domain ultrasound plane wave propagation for a desired angle is presented. The propagating angle is a function of the distance and the time-delay between the individual elements, and the propagating sound speed. In this model, the control parameter...

The natural ventilation of buildings provides improvement of internal comfort and air quality conditions leading to a significant reduction of the consumption of cooling energy.
In the present paper the air flow patterns, velocity and air temperature distributions inside a historical...

Crevice corrosion of stainless steel in chloride media was investigated based on an 11 species model. The role of parameters such as pH inside the crevice, external potential, chloride concentration of the bulk solution and crevice geometry was studied.
A thermodynamic criterion for...

Future hypersonic air vehicles will require a significantly expanded operating envelope. Fixed structural panels on these aircraft will be subjected to environments containing large temperature gradients and random acoustic excitations with high sound-pressure levels.
Panels exposed to...

We present a FEMLAB modeling study of an integrated, high-flow rate microfluidic pump for ferrofluids. Initial studies of these microfluidic devices have been performed using a onedimensional setup in MATLAB and later confirmed by corresponding simulations with FEMLAB 3.1 in partial differential...

Integration of surface acoustic wave (SAW) devices with nanostructures has gained interest in the development of sensors with high sensitivity. To better design nanostructure integrated SAW devices, it is essential to model three dimensional (3-D) SAW devices and analyze the wave propagation...

The Oldroyd-B family of viscoelastic fluids are notoriously difficult to model numerically. Standard Galerkin finite element methods are prone to numerical oscillations, and solutions break down as fluid elasticity increases. The situation can be remedied to a certain degree however through...

This paper describes the application of COMSOL Multiphysics to the modelling of Friction Stir Welding (FSW). The model predicts the heat generation from the material’s hot-deformation and thermal properties, the process parameters, and the tool and plate dimensions. The temperature...
