... presents the findings from that facility during the ignition and combustion of CO 2 -diluted syngas from reflected-shock ignition experiments. Pressures from 12 to 43 atm were studied in a 0.05 H 2 + 0.05 O 2 + 0.05 CO + 0.85 CO2 blend. Results from high-speed OH* imaging through the endwall showed...

.... Further investigation into the fundamental combustion kinetics of H2/CO/CO2 mixtures is required. Time-resolved speciation measurements for target species have been shown to better aid in improving the understanding of underlying chemical kinetics than global ignition delay time measurements. Therefore...

... refrigerants like CO2. However, the optimal heat rejection pressure for CO2 heat pump for a given load return temperature is significantly larger than that for HFC based heat pumps. This results in a higher throttling exergy loss for CO2 heat pump system than that in an equivalent HFC based system and is one...
