Thermal Natural Convection Simulations with COMSOL Multiphysics® in Comparison with Measurements

Published in 2014

In a laboratory setup a horizontal rod is heated on one side. By natural convection a stable temperature pattern is developed. Using the Nusselt formulation of the natural convection of cylindrical rods, the temperature distribution can be calculated. Only a good match of the simulations and the measurements can be reached when taking into account all the non-linear physics in the system. In this way the simulations are within 4% of the measurements. A nice showcase of multiphysics simulations.
