## Heat Induced Stress in a Brake Disc

## Heat Induced Stress in a Brake Disc

This multiphysics model examines temperature and heat induced stresses for one braking cycle in a brake disc assembly, and involves coupling of the stress-strain and heat transfer physics modes. The braking process consists of applying a brake pad to the front part of the disc which induces heat through friction, and …

## Natural Convection in a Square Cavity

This multiphysics model illustrates natural convection effects in a unit square domain using the Boussinesq approximation. The model involves a Navier-Stokes equations physics mode, representing the fluid flow with solid wall or no-slip boundary conditions everywhere. In addition a heat transfer physics mode is added …

## Heat Exchanger

## Heat Exchanger

This heat exchanger example illustrates the multiphysics modeling capabilities of FEATool. The model consists of a series of heated pipes surrounded by a fluid at a lower temperature, and features effects of both free and forced convection. Two types of physical phenomena are considered, fluid flow which is modeled by …

## Heat Transfer in a Ceramic Strip

## Heat Transfer in a Ceramic Strip

Two dimensional heat transfer of a ceramic strip with both radiation and convection on the top boundary. The ceramic has a thermal conductivity of 3 W/mK and the sides are fixed at a temperature of 900 °C while the bottom boundary is insulated. The surrounding temperature is 50 °C. The top boundary is exposed to both …

## Resistive Heating in a Tungsten Filament

## Resistive Heating in a Tungsten Filament

This example models resistive Joule heating where the resulting current from an applied electric potential will heat a thin spiral shaped Tungsten wire, such as can be found in incandescent light bulbs. The filament reaches an equilibrium temperature where the internal heat generation is balanced by radiative heat loss …

## Shrink Fitting of an Assembly

## Shrink Fitting of an Assembly

FEATool Multiphysics supports modeling heat transfer through both conduction, that is heat transported by a diffusion process, and also convection, which is heat transported through a fluid through convection by a velocity field. The heat transfer physics mode supports both these processes, and defines the following …

## Transient Heat Diffusion in a Rod

## Transient Heat Diffusion in a Rod

This example is a classic one-dimensional transient heat diffusion problem where a solid rod of unit length is kept at fixed temperature at the right end, T = 25, and losing heat from a constant outward heat flux qn = 1 at the other end. After the simulation the computed results can be compared with the analytic …
