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 ... Saiba Mais

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 ... Saiba Mais

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 ... Saiba Mais

Convection Cooking of Chicken Patties

When cooking food, such as a patty, in convection ovens there is a trade off in the heating method. If the patty is heated at a low oven temperature the cooking is slow and the patty dries out, resulting in a poor taste. If the patty is heated rapidly at a high temperature, it is ... Saiba Mais

Convection Cooling of Circuit Boards — 3D Natural Convection

The suite of models examine the air cooling of circuit boards populated with multiple integrated circuits (ICs), which act as heat sources. Two possible cooling scenarios are depicted: vertically aligned boards using natural convection, and horizontal boards with forced convection (fan ... Saiba Mais

Heat Generation in a Disc Brake

This example models the transient heating, and final temperature, of a disc brake of a car in brake-and-release sequence. It is important to model the transient heating and the following convective cooling to determine the minimum interval between a series of similar brake engagements. ... Saiba Mais

Flat Heat Pipe

Heat pipes are used in a wide range of applications for efficient cooling, for example in microelectronic systems, computer internals, and for large cooling devices in spacecraft industry. It combines the principles of heat conduction and phase change to get extremely efficient heat ... Saiba Mais

Tin Melting Front

This example demonstrates how to model phase transition by a moving boundary interface according to the Stefan problem. A square cavity containing both solid and liquid tin is submitted to a temperature difference between left and right boundaries. Fluid and solid parts are solved in ... Saiba Mais

Thermoelectric Cooler

Thermoelectric coolers are widely used for electronics cooling in various application areas, ranging from consumer products to spacecraft design. Exploiting the Peltier effect, they consist of several thermoelectric legs sandwiched between two thermally conductive plates, one cold and ... Saiba Mais

Marangoni Effect

Marangoni convection occurs when the surface tension of an interface (generally liquid-air) depends on the concentration of a species or on the temperature distribution. In the case of temperature dependence, the Marangoni effect is also called thermo-capillary convection. The Marangoni ... Saiba Mais
