Jeff D. Colwell, Ph.D., P.E. – Profile

Dr. Jeff Colwell is a Principal Engineer at Colwell Consulting where he specializes in the engineering analysis of thermal and combustion processes, especially the cause, origin, and propagation of fires and explosions.  Dr. Colwell has investigated fires and explosions in a wide array of applications including motor vehicles, residential and commercial structures, wildfires, and industrial complexes associated with the chemical, drilling, refining, and mining industries.  Technical issues addressed have included cause and origin determination, burn pattern interpretation, evaluation of ignition mechanisms, smoldering and self-heating, fire spread, smoke transport, smoke detector operation, building evacuation, fire department response, carbon monoxide poisoning, and handling of hazardous waste.  He also evaluates the design and performance of household appliances, heating and cooling equipment, and various other consumer products.  Dr. Colwell’s research has focused on fire dynamics, burn patterns, forced ignition mechanisms, including spark (electrostatic) and hot-surface ignition of combustibles, as well as ignition mechanisms associated with various types of electrical components.  He has also conducted research involving complex two-phase flows, liquid atomization, and droplet transport.

Prior to founding Colwell Consulting, Dr. Colwell was a Principal Engineer at Exponent where he worked for more than 18 years.  Dr. Colwell also held research positions at AlliedSignal Aerospace, the Combustion Laboratory at Arizona State University, the High Temperature Gas Dynamics Laboratory at Stanford University, and the Thermal Sciences and Propulsion Center at Purdue University.
