The Early Propagation And Burning Of Hydrogen In The Process Of The Deflagration To Detonation Transition, Rom Amasay
The Early Propagation And Burning Of Hydrogen In The Process Of The Deflagration To Detonation Transition, Rom Amasay
Honors Undergraduate Theses
The safe and efficient propagation of the Deflagration to Detonation Transition (DDT) is a topic that has been researched for many years due to its applications in Aerospace and Mechanical Engineering. DDT is when fire caused by the burning of fuel is accelerated to the upper CJ point on the Rankine Hugoniot curve due to instabilities in the flame and the turbulence caused by these instabilities. The complex flame dynamics that go along with DDT have ensured that the process is yet to be fully understood and defined. This research will work towards observing the early stages of burning hydrogen-air …

Experimental Study Of A Liquid Fuel Bluff Body Flame At Elevated Pressures, Karam Paul
Honors Undergraduate Theses
The purpose of this research was to operate a bluff body flame holder with the objective of stabilizing a flame at elevated pressures over a range of equivalence ratios. The ability to have a ground-based test rig capable of maintaining stable flames at high pressures and temperatures is critical in understanding flames present in modern jet engines and gas turbine technologies. The facility was reconfigured multiple times and the resultant flame was imaged within the optical test section. A converging nozzle was utilized to choke the flow and vary the operating pressures up to 5 atm. By regulating mass flow …
