Nonisothermal Laminar Flow in a Circular Tube

This verification model of nonisothermal laminar flow through a circular tube compares the heat transfer coefficient obtained from simulation with theoretical values based on Nusselt number correlation functions that can be found in the literature. Read More

Heat Conduction in a Finite 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. Read More

Out-of-Plane Heat Transfer for 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 one end and is isolated at the other. A surrounding liquid ... Read More

Thermoelectric Leg

A thermoelectric leg is a fundamental component of a thermoelectric cooler (or heater). For example, a thermocouple is a thermoelectric module typically made of two thermoelectric legs: one made of p-type and of one n-type semiconductor material which are connected in series electrically ...

Concentric Tube Heat Exchanger

Finding the right dimensions for a heat exchanger is imperative to ensure its effectiveness. Other properties must also be considered in order to design a heat exchanger that is both of the right size and provides heated or cooled fluid of the right temperature. The Concentric Tube Heat ...

Inline Induction Heater

Ferritic stainless steels have become more and more popular in the food industry because of their relatively low and stable price and due to the absence of nickel in their components. Their resistance to corrosion can be improved by adding chromium or molybdenum, and their magnetic ... Read More

Radiative Cooling of a Glass Plate

When producing glass, the glass melt is cooled down through radiation to form the final shape, subjecting it to stresses. Numerical treatment of radiative heat transfer, using the Radiative Transfer Equation (RTE), helps to optimize this process. COMSOL Multiphysics provides three ... Read More

Radiative Heat Transfer in Finite Cylindrical Media

These models use the Discrete Ordinates method (DOM) and P1 approximation 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 accurate results, which are needed in ... Read More

Nonisothermal Turbulent Flow over a Flat Plate

This verification model of nonisothermal turbulent flow over a flat plate compares the heat transfer coefficient obtained from simulation with theoretical values based on Nusselt number correlation functions that can be found in the literature. Read More

Isothermal Box

This example solves the heat transfer in an isothermal box aimed at transporting refrigerated articles such as medical materials for 24 hours. In this case, the box not only has to keep the content cold in a long period of time, but also has to respect a storage temperature restriction. ... Read More
