Simulation of a Microrobot, 3DSimulation of a Microrobot, 3D

A microrobot's leg, which structurally moves due to the rapid application of heat, is modeled in this example. Heat is generated by an electric current and propagates by conduction through the leg and, due to thermal expansion and...

Thermal Modeling of a Microchannel HeatsinkThermal Modeling of a Microchannel Heatsink

Thermal management has become a critical aspect of today’s electronic systems, which often include many high-performance circuits that dissipate large amounts of heat. Many of these components require efficient cooling to prevent...

Fluid DamperFluid Damper

Fluid dampers have wide applications, for example in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations. A fluid damper works by dissipating mechanical...

Heat SinkHeat Sink

This example models the cooling characteristics of the n19 aluminum heat sink from Alpha Company Ltd in Japan. The model studies the heating resistance under different air-flow rates using a semi-empirical formula for the heat transfer...

Heat Transfer in a Silica Block Coated with a Copper LayerHeat Transfer in a Silica Block Coated with a Copper Layer

In this time-dependent model, a silica block of glass, coated with a thin copper layer is subjected to a heat flux. Copper is a highly conductive material, while the silica glass is of poor thermal conductivity, which sets up an...

Heat Transfer in a Surface-Mount Package for a Silicon ChipHeat Transfer in a Surface-Mount Package for a Silicon Chip

This model investigates the stationary temperature distribution in an integrated circuit mounted close to a hot component. The model uses the Heat Transfer interface and its Highly Conductive Layer feature.

Heat Transfer in a Thin PlateHeat Transfer in a Thin Plate

This example models heat transfer in a thin rectangular metal plate. Because the plate’s thickness is only 1/100 of its length and width, you can simulate the process using a 2D approximation. The plate has a fixed temperature at...

Heated Vertical PlateHeated Vertical Plate

This model shows the application of COMSOL Multiphysics in modeling the non-isothermal flow of gases at relatively low flow velocities. Here, a vertical plate is held at a constant temperature, which is higher than that of the...

Power TransistorPower Transistor

This model simulates a system consisting of a small part of a circuit board containing a power transistor and the copper pathways connected to the transistor. The purpose of the simulation is to determine the transistor's operating...

Radiative Heat Transfer in a Utility BoilerRadiative Heat Transfer in a Utility Boiler

This model uses the discrete-ordinates method (DOM) to analyze the radiative heat transfer in a utility boiler with internal obstacles. DOM is one of the most useful radiation models for prediction of radiative heat fluxes on the furnace...
