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 and in parallel thermally.

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, the behavior of the temperature and heat flux within the furnace and on the heat surfaces can be easily obtained ...

Temperature Field in a Cooling Flange

A cooling flange in a chemical process is used to cool the process fluid, which flows through the flange. The surrounding air cools the flange via natural convection. In the stationary model, the forced convection to the process fluid is modeled using a constant heat transfer coefficient. The natural convection cooling is modeled using tabulated empirical transfer coefficients that are ...

Parameterized Window and Glazing Geometry

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The international standard ISO 10077-2:2012 deals with thermal performance of windows, doors and shutters. It ...

Optimizing a Thermal Process

A thermal processing scenario is modeled whereby two heaters raise the temperature of a gas flowing through a channel. The Optimization Module is used to find the heater power to maximize the outflow temperature, while maintaining a constraint on the peak temperature at the heaters themselves.

A Warm Sunny Day on the Beach under a Parasol

This model illustrate how to model thermal effects of the sun as an external radiative source and considers wavelength-dependent surface emissivities. Two styrofoam coolers are exposed to ambient conditions. A parasol provides shade for one of the coolers for most of the day. The temperature of the beverage cans in the coolers is computed over time.

Radiative Heat Transfer in Finite Cylindrical Media—P1 Method

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 ...

Shell Conduction

This model simulates a static analysis of heat conduction in a thin conductive shell. This is a benchmark model where the result is compared with a NAFEMS benchmark solution.

Convective Cooling of a Potcore Inductor

The inductor is a common component in a variety of electrical devices. Its applications include power transformation and measurements, and it can also be used together with capacitors to create oscillators. In small devices with many components, such as in laptops, heat generation can be a problem and must be accounted for in the design. This axi-symmetric model studies the heat transfer in ...
