In the absence of such a source term, the solutions collapse onto the recent literature. Results clearly demonstrate how...

... of an existing industrial heat sink was minimized. Simple optimum results such as those with single fins above are difficult to obtain with heat sinks due to a larger number of variables and constraints. Such design is constrained not only by volume or mass, but also by the available fan power. An optimal...
