LTC Samuel Cowart

Assistant Director, Chemical Engineering Program


LTC Cowart is the Course Director and instructor for CH485 (Heat & Mass Transfer), CH364 (Chemical Reaction Engineering) and CH362 (Mass & Energy Balances).  He commissioned as a field artillery officer in 2002 from the University of North Dakota, where he also earned a B.S. degree in chemical engineering.  His operational assignments led to duties from cannon platoon leader to battalion executive officer in light and heavy field artillery, cavalry, and infantry battalions, with operational deployments to Iraq, Jordan, the UAE, and Syria.

He completed M.S. and Ph.D. studies at the University of North Dakota where he concentrated on electrochemical deposition of refractory metals from ionic liquid electrolytes and computational fluid dynamics studies of oxy-fuel combustion.

LTC Cowart has previously served as a Hockey Officer Representative, a member of the USMA Admissions Committee, a Course Director for CH101, and a Department Academic Counselor.

Ongoing Research Projects

LTC Cowart’s research interests focus on the use of computational fluid dynamics (CFD) to explore combustion phenomena.  He is currently investigating mechanisms of deflagration-to-detonation transitions (DDT) of simple hydrocarbon fuels with application toward development of feasible pulse detonation engines.  Additional research interests include computationally efficient combustion reaction mechanisms, soot production from hydrocarbon flames, and heat transfer aspects of premixed and non-premixed oxy-fuel combustion.
