This model evaluates the temperature distribution in 3 buried cables in a situation where the soil surface temperature is known. The temperature profile obtained with a thermal circuit approach for the cables is compared with a FEM approach. The thermal circuit properties are established ... En savoir plus
This model demonstrates the transport of grains using a screw conveyor. The grains enter the conveyor through a chute and are transported over an incline by a rotating screw. This model also demonstrates how to build and run a model method that evaluates the mass flow rate. En savoir plus
This example models a split-and-recombine mixer channel in which a tracer fluid is introduced and mixed by multilamination. Diffusion is removed from the model using an extremely low diffusion coefficient so that any numerical diffusion can be studied in the lamination interfaces. The ... En savoir plus
This example uses the thermal expansion of a laminated composite shell model to demonstrate the use of the feature Thermal Contact, Interface, applied on interfaces between layers in a laminated composite shell. The first study is computed neglecting this additional thermal resistance in ... 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
An important and interesting phenomenon with supersonic flows are expansion fans, which take place when the flow encounters a convex or expansion corner. The direction of the flow changes smoothly across the fan, while the Mach number increases. This 2D example models an expansion fan ... En savoir plus
A simple model for groundwater contamination portrays a well that is bored into an aquifer. The aquifer consists of a partially saturated layer and a fully saturated layer. The model investigates how much of the contaminant ends up in the well after a contaminant is introduced in the ... En savoir plus
This model presents the flow noise generated by flow past the so-called tandem cylinder configuration. The test is part of the “First Workshop on Benchmark problems for Airframe Noise Computations”. The tutorial model shows the steps involved in a flow-induced noise simulation in COMSOL ... En savoir plus
1D model of a thermal energy storage (TES) system consisting of a packed bed of pellets. Three approaches for heat transfer in porous media are compared: A one-equation local thermal equilibrium (LTE) model A two-equations local thermal nonequilibrium (LTNE) model A multiscale ... En savoir plus
This example studies heat transfer in a composite two-dimensional structure. Four materials with distinct thermal conductivities k compose the structure. The top and bottom boundaries are facing environments respectively at 0°C and 20°C. The temperature distribution and the heat flux ... En savoir plus
