Thermal Analysis Using SOLIDWORKS: FEA vs CFD | GoEngineer The convection coefficient, formally denoted by h, is what is needed for our thermal analysis in SOLIDWORKS Simulation. We can use the previous setup for this. The main reason why CFD software is needed becomes apparent after seeing the differences in SOLIDWORKS Simulation temperature plots and the surface heat flux plot with SOLIDWORKS Flow Simulation. Heat transfer by radiation. The kinematic viscosity of a fluid reveals information about the rate at which momentum may diffuse through the fluid because of molecular motion. FP By Frank Phelps 02/13/15. The rapid motion of the fluid particles over the face of the solid maximizes the temperature gradient and increases the rate of heat exchange.

The actual mechanism of heat transfer through the boundary layer is taken to be conduction, in the y-direction, through the stationary fluid next to the wall being equal to the convection rate from the boundary layer to the fluid. Convection is simply conduction from a solid to a fluid. Electrothermal Simulation of Busbars using EMS for Solidworks Once calculated, Ra is then used to determine which equation is appropriate for calculating the average Nusselt number (Nu) (because of space restrictions a complete list of variable definitions can be found in the table at the end of this blog). To provide feedback on individual help topics, use the Feedback on this topic link on the individual topic page. Convection is the heat transfer mode in which heat transfers between a solid face and an adjacent moving fluid (or gas).

Most textbooks will say that fluid properties should be looked-up and/or calculated at an average temperature (skin temperature and ambient temperature), but in my experience it is more accurate to look-up fluid properties at T (= 20 C). Under the simulation tab, click the drop-down menu under the "Study Advisor" button, and click "New Study." This will bring you to another drop down menu where . Our thermal analysis has no gradient across the outer surface while the CFD result plot is much more detailed, which is precisely the reason why applying a convection boundary condition in a thermal analysis is an averaged approximation and should only be used for global trends. Define the Convection Coefficient as 250 W/(m^2.K), Define Bulk Ambient Temperature (the temperature that surrounds the model) as 300 Kelvin (K). Thermal Analysis with SOLIDWORKS Simulation textbook Step 1: Start a New Thermal Study. In this thermal analysis we have a long hollow copper pipe (20 mm OD and 15 mm ID) that is transporting a hot fluid (80 C) through a body of water (20 C). We are not quite ready to put this number into our thermal analysis. Where v and are the kinematic viscosity and thermal diffusivity of the fluid respectively. While the known correlations for Nu and various geometry are limited to simple shapes (flat plates, cylinders, spheres, etc. In this example, we mainly need to change the properties. the most typical exceptions would be when: (1) there is no convective heat transfer mechanism in the problem that is being solved because likely the object (s) are in a vacuum and only transport heat through conduction and radiation; or (2) the thermal solution does not require a great deal of accuracy reflecting a physical test perhaps in the How to Set Up a Thermal Study in SOLIDWORKS Simulation - GoEngineer We will also assume the body of water is static and, therefore, the convection is defined as natural rather than forced convection.
