Similitude in electronics cooling: scaling and design of experiments

Summary form only given. A tutorial that establishes procedures that can be employed to identify the variables that are important to characterizing aero-thermal problems is summarized. The discussion ranged from a seat-of-the-pants manipulation of experimental data to a more rigorous derivation of the minimum number of variables required to describe a problem. Practical sample problems applied to electronics cooling geometries were presented as examples of the process of variable identification
