RF-Heated Hot Wall Furnace for Semiconductor Processing

Furnace reactors are used in the fabrication of semiconductors to grow layers on wafers. These can also be used for epitaxial growth, which is a key technology for fabrication of electrical devices. A silicon carbide growth takes place in graphite susceptors at very high temperatures (~2000 oC), which are heated with RF coils. The design of the chamber is crucial to reach a uniform ...

Thermal Stress Analysis of a Turbine Stator Blade

The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore be carefully designed to be able to withstand thermal stresses, vibrations and loads asserted by the fluid rushing through the turbine. If a component fails, the high rotational speeds can result in a complete rupture of the whole ...

The Magnus Effect

The Magnus effect explains the curl that soccer players can give the ball, resulting in the enjoyable goals that we can see in every World Cup™. This model looks at the Magnus effect in the laminar and turbulent flow regimes for transient and stationary flows. It also discusses the simulation results and relates them to experimental measurements on soccer balls found in the literature.

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

All integrated circuits—especially high-speed devices—produce heat. In today’s dense electronic system layouts heat sources are many times placed close to heat-sensitive ICs. Designers of printed-circuit boards often need to consider the relative placement of heat-sensitive and heat-producing devices, so that the sensitive ones do not overheat. One type of heat-generating device is a ...

Heating of a Slab

This simple example covers the heating of a finite slab and how the temperature varies with time. We will set up the problem in COMSOL Multiphysics after which we compare the solution to the analytical solution.

Using the Curvilinear Coordinate Interface for Heat Transfer Modeling

This model and presentation shows how to model anisotropic properties of fibers in a heat transfer simulation. Because the fibers orientation is not easy to define explicitly, the curvilinear coordinate interface is used to define the fiber orientation. The fibers have high thermal conductivity in the fiber direction and low conductivity in the perpendicular direction.

Simulation of Multiphysics Contact in a Power Conductor

This model illustrates how to implement a multiphysics contact. It models the thermal and electrical behavior of two contacting parts of a switch. The electrical current and the heat flow from one part to the other only through the contact surface. The contact switch device has a cylindrical body and plate hook shapes at the contact area. There, the thermal and electrical apparent resistances are ...

Radiative Heat Transfer in Finite Cylindrical Media

This model uses the Discrete-Ordinates method (DOM) to solve a 3D radiative transfer problem in an emitting, absorbing, and linear-anisotropic scattering finite cylindrical medium. Using the S6 quadrature of DOM leads to faster and more accurate results, which are needed in combined modes of heat transfer. The calculated incident radiation and heat fluxes agree well with published results ...

Power Transistor

In every system where there is conduction of electric current, and where the conductivity of the material is finite, there will be electric heating. Electric heating, also referred to as Joule heating, is in many cases an undesired by-product of current conduction. This model simulates a system consisting of a small part of a circuit board containing a power transistor and the copper pathways ...

Copper Layer on Silica Glass

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 highly-varied temperature differential. The model must therefore account for a highly conductive layer. This is done, using a the Highly Conductive Layer feature in ...
