While many electronic devices have power densities that require forced air flow, a significant number of systems can still utilize solely natural (passive) convective cooling.
The reliability and quietness of passively cooled systems is especially attractive for consumer devices, so investigating these cooling options is a valuable portion of the design process. Effective investigation of natural convection cooling requires efficient simulation. Simulation experts demonstrate how the physical characteristics of Rayleigh-Benard convection cells will be leveraged to maximize the speed of natural convection analyses that involve narrow internal air gaps.
Using STAR-CCM+ trainers demonstrate how to maximize the speed of each simulation. Techniques shown teach users to investigate more design options so the most effective cooling design can be selected.
