 Cross-Flow Heat ExchangerThis model solves the fluid flow and heat transfer in a micro heat exchanger made of stainless steel. These types of heat exchangers are found in lab-on-chip devices in biotechnology and micro reactors, for example for micro fuel cells.... Disk-Stack Heat SinkThis problem follows a typical preliminary board-level thermal analysis. First perform a simulation of the board with some Integrated Circuits (ICs). Then, add a disk-stack heat sink to observe cooling effects. Finally, explore adding a... Heat Transfer in a Thin PlateThis example models heat transfer in a thin rectangular metal plate. Because the plate’s thickness is only 1/100 of its length and width, you can simulate the process using a 2D approximation. The plate has a fixed temperature at one... Heated Vertical PlateThis model shows the application of COMSOL Multiphysics in modeling the non-isothermal flow of gases at relatively low flow velocities. Here, a vertical plate is held at a constant temperature, which is higher than that of the... Non-Isothermal Flow Around a Cooling DeviceThis model shows the application of COMSOL Multiphysics in the modeling of non-isothermal laminar flow of fluids (in this case a gas). The model assumes that the expansion work done by the gas is negligible, that the variations in... Plate Heat ExchangerThe model has its emphasis on heat transport in a very small heat exchanger which is commonly used in the field of Micro Electro Mechanical Systems, MEMS. In this case it might be a reactive processes that needs heating. The heat... Radiative Heat Transfer in Finite Cylindrical MediaThis 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... Temperature Field in a Cooling FlangeA 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... Thermal Contact Resistance Between an Electronic Package and a Heat SinkThis example reproduces parts of the study of Ref. 1 on the thermal contact resistance at the interface between a heat sink and an electronic package. Eight cooling fins equip the cylindrical heat sink and contact is made at the radial... Thermal Modeling of a Power TransformerThis model describes the temperature distribution in a coil-shaped power transformer which is cooled by forced flow of transformer oil from the bottom. The properties of the oil varies strongly with temperature, making modeling of the...
