Professional Experience

Dr. Morton joined the Department of Integrated Engineering at Southern Utah University in the Fall of 2009. After completing his Ph.D. in Mechanical Engineering in 1997, he began work at General Electric Power Systems as a Lead Fluid Mechanics Design Engineer, performing turbine blade design, turbine hot section gas temperature prediction, cooling and leakage flow assessment, turbine component flow modeling, and gas turbine thermodynamic cycle analysis for GE’s product line fleet and for modifications and upgrades. In 2000, he received GE’s Engineering Services Award for development of GE’s Turbine Outage Optimizer, a design tool for analyzing GE’s modifications and upgrades. In 2003, he received GE’s Patent Award for co-development of GE’s Gas Turbine Simulator Tool. In 2007, he joined the University of Tennessee Space Institute as Research Assistant Professor, conducting research in the field of bluff-body aerodynamics and vortex-dominated flows. His research interests include bluff-body aerodynamics, rotating machinery and turbine blade design, and mathematical methods for vortex-dominated flows. His recent research on engine flows was recognized as the 2013 Top Downloaded Paper of the International Journal of Engine Research.

Research on Vortex Rings

Understanding the primary flow characteristics of a vortex can guide both conceptual designs and CFD studies of combustion chambers for the energy and automotive industry. In the following two streamline patterns from Dr. Morton's current research on vortex rings with swirl, wider spacing between streamlines indicates regions of lower velocity, and tighter spacing indicates regions of higher flow velocity. The ratio f of the polloidal frequency to the toroidal frequency of a fluid particle traveling on the outside streamline is 3 in the vortex ring on the top, and 1/4 in the vortex ring on the bottom.
