This paper presents a multiphysics model to the convective, conductive and radiative heat transfer for the thermoelectric modules (TEMs), which are used to convert heat flux into electrical current. The model basically consists of heat transfer in solids, heat transfer in thin shells, ... Read More

This work is a first evaluation of the validity of the frozen rotor approximation for the simulation of a stirred beaker. The agreement is good, further analysis will be carried before using the model to optimize labscale setup dedicated to IL electrochemistry. Read More

We present a numerical investigation on a metal foam radiator in natural convection. Metal foams are innovative lightweight materials with unique heat dissipation properties. COMSOL Multiphysics® has been used to reproduce experimental data and generate an optimized geometry to maximize ... Read More

Si-infiltrated SiC porous composites exist in different forms composed of cores of cellular ceramic and skin plates of ceramic matrix composites. Due to high thermal conductivity, low coefficient of thermal expansion, high elastic modulus and high strength, the final product can be a ... Read More

The primary devices used for testing the aerodynamic properties of aircraft constructions are aerodynamic and water tunnels. They enable to visualize the flow and measurement of the moving liquid parameters, which serve to determine aerodynamic characteristics. However, they entail ... Read More

The boundary layer flow above an isothermal flat plate inclined at a small angle to the horizontal is analyzed. Inclination effects are initially investigated as a perturbation to the horizontal flow by obtaining a fourth order series solutions valid near the leading edge of the plate ... Read More

Usually, when calculating the blood flow in cerebral arteries and intracranial aneurysms, blood is modeled as a Newtonian fluid, neglecting its shear-thinning behavior. Since flow diverting devices slow down the blood flow in the aneurysm sack, the accuracy of this assumption had to be ... Read More

Ultrasonic levitation is a novel technology for contactless handing of various objects. It is already used in various manufacturing processes where it is important to keep untouched surface. In this paper we introduce a model of so-called near-field ultrasonic levitation which allows ... Read More

In addition to using advanced functions built-into the engine of the COMSOL Multiphysics® software, we integrate dynamic properties of rotating components that are measured or pre-computed. Here, it is shown how to integrate fluid-film characteristics and take advantage of post ... Read More

The acoustic scattering through a circular orifice plate in a duct with low Mach number flow (M=0.1) is computed using the Linearized Navier-Stokes physics interface of COMSOL Multiphysics®. The work by Kierkegaard et al. is extended to account for higher order acoustic modes, i.e., ... Read More
