Buoyancy Flow in Air

This example studies the stationary state of free convection in a cavity filled with air and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, set in a range to keep the flow laminar. En savoir plus

Topology Optimization of a Heat Exchanger with Laminar Flow

This model demonstrates topology optimization of a 2D heat exchanger with laminar flow. The flow is pressure driven and the objective is to maximize the heat transfer. The density method is used with the (now) classical approach of a single design variable and two flow interfaces. ... En savoir plus

Thermal Modeling of a Microchannel Heat Sink

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 overheating. Some of these components, such as processors, ... En savoir plus

Thermomechanical Analysis of a Surface-Mounted Resistor

The drive for miniaturizing electronic devices has resulted in today’s extensive use of surface-mount electronic components. An important aspect in electronics design and the choice of materials is a product’s durability and lifetime. For surface-mount resistors and other components ... En savoir plus

Hepatic Tumor Ablation

One method for removing cancerous tumors from healthy tissue is to heat the malignant tissue to a critical temperature that kills the cancer cells. This example accomplishes the localized heating by inserting a four-armed electric probe through which an electric current runs. Equations ... En savoir plus

Viscous Heating in a Fluid Damper

Fluid dampers are used in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations, among many other applications. Fluid dampers work by dissipating the mechanical energy into heat. This model shows the phenomenon ... En savoir plus

Thermoelectric generator

In this model, we show how to model Seebeck effect which works as a thermoelectric generator. Seebeck effect is a phenomena where the difference in temperature of a material leads to a potential difference. The potential drawn in this model was compared with the paper by Jaegle (Example ...

Air-Cooled Battery Energy Storage System

Tutorial model of an air-cooled battery energy storage system (BESS). The model includes conjugate heat transfer with turbulent flow, fan curves, internal screens, and grilles. It features several interesting aspects: Fully parameterized geometry, which can be modified for different ... En savoir plus

Radiative 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 walls of a combustion chamber. With this model, ... En savoir plus
