During professional wine tasting, several samples of wine are judged in one session. It is important that each sample is covered, since evaporation of ethanol and water will change the taste. This model simulates the evaporation of ethanol and water from a wine glass. Evaporation of ... En savoir plus
In this example, a dynamic analysis of a three-cylinder reciprocating engine is performed to investigate stresses generated during operation, thereby permitting identification of the critical components. Demand for high power output relative to the weight of the engine requires careful ... En savoir plus
When designing oxygen masks for delivering respiratory support to patients via BiPAP and CPAP, multiphysics modeling helps visualize the flow pattern inside the mask for a given design. From there, it is possible to estimate oxygen consumption, carbon dioxide accumulation, and ... En savoir plus
This app demonstrates the following: Geometry parts and parameterized geometry A results table form object containing outputs Finned pipes are used for coolers, heaters, or heat exchangers to increase heat transfer. They come in different sizes and designs depending on the ... En savoir plus
This example investigates the electrical performance of a cascaded cavity filter operating in the millimeter-wave 5G band with temperature changes. The thermal variations result in structural deformations of the structure. Thus, the resonant frequencies of the filter elements (cavities) ... En savoir plus
When electrical energy is converted into mechanical work in an electrical motor, the "wasted" energy that causes device heating is usually referred to as loss. The ratio of useful work to input energy, or the efficiency of the motor, is an important property for the overall energy ... En savoir plus
This tutorial demonstrates the use of the Heat and Moisture Flow predefined interface for the modeling of heat transfer and moisture transport in a turbulent air flow, with the quantification of evaporation and condensation on surfaces, and the automatic handling of the associated latent ...

In general, there are two classes of ventilation: mixing ventilation and displacement ventilation. In displacement ventilation, air enters a room at the floor level and displaces warmer air to achieve the desired temperature. Heating sources in the room can include running electronic ...

This example is about the modeling of the fiber drawing process. Thermal fiber drawing is a process in which a comparatively thicker structure is heated and drawn into extended lengths of microstructured fiber. This process is done by passing them through the furnace and pulling them ... En savoir plus
This tutorial shows how to use the Radiative Beam in Absorbing Media interface (Heat Transfer Module) to model the attenuation of a laser light going through a sample of silica glass, and the heat source generated by the absorption. En savoir plus
