This tutorial model shows how a plate-fin heat exchanger made of aluminum is used to cool down hot oil with colder air. In order to maximize heat transfer, the heat exchanger is made of a porous aluminum matrix in which the hot oil flows. Heat is conducted through aluminum fins in ... En savoir plus
This model presents a 2D axisymmetric dipolar microwave plasma source sustained through resonant heating of the electrons. This is known as electron cyclotron resonance (ECR), which occurs when a suitable high magnetic flux density is present along with the microwaves. This is an ... En savoir plus
In small PEM fuel cell systems (in the sub-100 W range) no active devices for cooling or air transport are normally used. This is due to the desire to minimize parasitic power losses from pumps and fans, and to reduce the system complexity, size, and cost. The reactants at the cathode ... En savoir plus
In this model, a microwave absorber is constructed from an infinite 2D array of pyramidal lossy structures. Pyramidal absorbers with radiation-absorbent material (RAM) are commonly used in anechoic chambers for electromagnetic wave measurements. Microwave absorption is modeled using a ... En savoir plus
The External Material functionality makes it possible to program your own material models for cases when the built-in material models are not sufficient. For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic ... En savoir plus
Microlaboratories for biochemical applications often require rapid mixing of different fluid streams. At the microscale, flow is usually highly ordered laminar flow, and the lack of turbulence makes diffusion the primary mechanism for mixing. While diffusional mixing of small ... En savoir plus
Patch antennas are becoming more common in wireless equipment, like wireless LAN access points, cellular phones, and GPS handheld devices. The antennas are small in size and can be manufactured with simple and cost-effective techniques. Due to the complicated relationship between the ... En savoir plus
This model example shows how to model nonlinear propagation of 1D finite-amplitude Acoustic waves in fluids using Acoustics Module of COMSOL Multiphysics. The model is based on the 2nd order Westervelt equation. The one dimensional nonlinear wave equation is solved in the time domain by ... En savoir plus
The suspension of a loudspeaker is designed to keep the membrane in place and avoid any rocking movement of the voice coil. At low frequencies, where the displacement of the membrane is significant, the stiffness of the suspension varies along the movement of the voice coil. This ... En savoir plus
This model represents a test case of a flow in an elastic tube which is present in several applications. This specific case models viscoelastic flow and represents steady flow in a channel in which part of the upper wall is replaced by an elastic plate subjected to an external pressure. ...
