In this model, a microwave absorber is constructed from an infinite 2D array of pyramidal lossy structures. Pyramidal absorbers with radiation-absorbent material (RAM) are commonly used in anechoic chambers for electromagnetic wave measurements. Microwave absorption is modeled using a ... Mehr lesen
This model addresses the concept of wireless power transfer by studying the energy coupling between two circular loop antennas tuned for UHF RFID frequency whose size is reduced using chip inductors. The circular loop antenna provides inherent inductive coupling by its shape, and it can ... Mehr lesen
This example investigates the electrical and thermal characteristics of a plasma DC arc created in a point-to-plane configuration. The discharge is assumed to be in local thermodynamic equilibrium. The plasma is considered a conductive fluid medium and is modeled using a ... Mehr lesen
Transport which is purely diffusive in nature can be modeled using a Brownian force. This model shows how to add such a force in the Particle Tracing for Fluid Flow physics interface. Particle diffusion in a fluid is modeled with the diffusion equation and the Particle Tracing for Fluid ... Mehr lesen
For more than 50 years, it has been known that neutrally buoyant particles in a flow channel tend to converge to specific locations in the channel cross section. For a cylindrical pipe, or two parallel planes carrying a Poiseuille flow, the equilibrium position is about 0.6 times the ... Mehr lesen
During quenching of steel, austenite decomposes into phases such as ferrite, pearlite, bainite, and martensite. A common way to illustrate the phase transformation characteristics of a particular steel alloy is to use transformation diagrams. Two of the most commonly used diagram types ... Mehr lesen
In nature, geckos use dry adhesion forces to climb walls. They have inspired researchers to develop synthetic gecko foot hairs to be used in, for example, robot applications. This model contains the nano/micro hierarchy of a synthetic gecko foot hair, where cantilever beams both in nano ... Mehr lesen
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. Mehr lesen
Dieses Modell behandelt die freie Konvektion und den Wärmetransport eines Glases mit kaltem Wasser, das sich auf Raumtemperatur erwärmt. Zu Beginn haben das Glas und das Wasser eine Temperatur von 5 °C und werden dann auf einen Tisch in einem Raum mit 25 °C gestellt. Die nicht-isotherme ... Mehr lesen
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, ... Mehr lesen
