A handful of fan definitions are included with Flow Simulation by default, but additional representations of cooling fans (and even water pumps) can be user-defined by inputting a static-pressure curve. Click here for information about technical support. In this type of analysis, we are only interested in the thermal conditions of the body when it reaches a state of thermal equilibrium. All rights reserved. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and transfer of energy by phase changes. Design Generator Inc. The results for a conjugate heat transfer test "Lamp with reflector" model are shown in Image 8, where all three heat transfer modes were used in the solution. SOLIDWORKS simulation allows you to determine product durability, optimize the design, determine natural frequencies, product mechanical resistance, and more. We would like to simulate this using solidworks and would like to see the temperature profile with time. Terms of Use Thermal radiation is the thermal energy emitted by bodies in the form of electromagnetic waves because of their temperature. Anytime there are many iterations required, such as when attempting to optimize a geometry, users can take advantage of the in-built parametric study functionality, which allows creating a virtual design of experiments (DoE). The heat sink is inserted in the duct by the part of the fins in order to capture the heat flow through the duct. All rights reserved. Figure 7.
