This model shows how you can use the Non-Isothermal Pipe Flow interface together with the Heat Transfer in Solids interface to model the cooling of a injection molded polyurethane part for a car steering wheel. The equations describing the cooling channels are fully coupled to the heat ... En savoir plus
Every electrical device has some resistance. That is, when a voltage difference is applied across any two terminals of the device, there will be a directly proportional current flow. This model demonstrates how to compute the resistance of a short section of copper wire. The convergence ... En savoir plus
In this example, wrinkling is studied in a cylindrical membrane of nonuniform thickness under axial and pressure loading. The membrane is modeled as an incompressible Mooney–Rivlin material. During axial stretching, certain portions of the membrane undergo wrinkling; however, the ... En savoir plus
In this example, a spring-loaded valve-opening mechanism consisting of a rocker arm and a radial cam is studied. All of the system components are modeled as rigid and are connected through prismatic, hinge, and slot joints. The cam-follower connection as well as other joint connections ... En savoir plus
Piezoelectric valves are frequently employed in medical and laboratory applications due to their fast response times and quiet operation. Their energy efficient operation, also dissipates little heat, which is often important for these applications. This model shows how to model a ... En savoir plus
A surface mount resistor is subjected to thermal cycling. The difference in the thermal expansion of different materials will introduce stresses in the structure. The solder which connects the resistor with the printed circuit board is seen as the weakest link in the assembly. It ... En savoir plus
This example extends the analysis made in the model Electrodeposition on a Resistive Patterned Wafer by including the diffusion and convection of copper ions in the electrolyte. The coupled mass transport convection-diffusion effects are of interest in this type of reactor since they ... En savoir plus
Maximizing product yield is a main task in chemical reaction engineering. This can be especially challenging if the desired product, once formed, can be consumed by further reactions. This example investigates such a series reaction as it occurs in a tubular reactor. You will start by ... En savoir plus
In a cylindrical or prismatic battery cell, the active layers, current collector metal foils and separators are wound into a “jelly roll”. Additional tabs (metal strips) are welded to the current collector foils in order to conduct the current to the exterior of the cell can. The ... En savoir plus
This model shows a setup of two parallel wires with a constant current running through both. Their cross-sections are successively reduced until a set force per unit length is reached. En savoir plus
