Mixtures of ammonia and hydrogen have received significant interest recently as a possible replacement for hydrocarbon fuels. A toroidal jet-stirred reactor (TJSR) was designed and constructed to combust these mixtures in the well-stirred limit for validating chemical kinetic mechanisms and improving the current understanding of the combustion properties of this fuel. The TJSR was designed to achieve low residence times – on the order of 5 ms – to approximate the conditions in an aircraft gas turbine combustor. Simulations were conducted to determine mass flow rates, expected emissions output, and expected lean blow out. Based on these results, material studies were conducted to determine the best materials for each of the TJSR's components. Thermomechanical were conducted to determine the expected temperature distribution and thermal expansion during operation. Casing components were designed to seal the gases in the reactor as well as provide means to connect it to a pressure vessel or other piping. This work will allow for chemical mechanism validation of lean blowout in ammonia-hydrogen mixtures while laying the foundation for future high-pressure testing of such mixtures up to 60 bar.
