Abstract
Performing experiments that properly simulate the conditions of interest usually requires matching various relevant nondimensional parameters.  Determination of these parameters generally involves the simple, but sometimes neglected task of nondimensionalization.  Nevertheless, a thorough analytic approach can save time and frustration in the laboratory.  In this talk, I will walk through a simple application of nondimensionalization as it relates to a decades-old problem, revealing information that surprisingly, had been largely ignored and has the potential to improve experimental simulations of gas turbine film cooling.  Although the example is directly applicable to gas turbine heat transfer, the lessons can be applied to a broad array of disciplines.

About the Speaker
James (Jay) Rutledge is an Associate Professor of Aerospace Engineering and Senior Military Faculty in the Department of Aeronautics and Astronautics at the Air Force Institute of Technology. In this position, he supervises graduate research connected to air breathing propulsion and thermal management while teaching graduate coursework in fluid dynamics and convection heat transfer. He is currently on a sabbatical assignment at the Air Force Research Laboratory’s Turbine Engine Division where he directs development of alternative engine concepts. Jay has published 28 journal articles, holds a US patent, is a licensed professional engineer in the State of Texas and is an associate editor for the ASME Journal of Turbomachinery.
