Blending hydrogen has proven an efficient method to enhance the combustion stability of gaseous ammonia flames. Heat release rate (HRR), as an important parameter to indicate combustion process, is hard to be directly measured and highly dependent on the fuel components, equivalence ratios, and operation conditions. This paper presents a comprehensive study on developing a general HRR surrogate (HRRS) for ammonia-hydrogen premixed flames under various conditions. Firstly, reaction mechanisms for
Alcohol-to-Jet Synthetic Paraffinic Kerosene (AtJ-SPK), an approved sustainable aviation fuel (SAF) by blending with conventional Jet A fuel, has recently been experimentally studied, and detailed mechanisms have been developed to describe its combustion behavior. The present study aims to develop reduced mechanisms of AtJ-SPK and its blends with Jet A for high-fidelity and computationally affordable computational fluid dynamics. Specifically, two reduced mechanisms were developed for pure AtJ-S
High nitrogen emission is one of the significant challenges for the utilization of ammonia (NH 3 ) as a clean fuel. Although the reaction kinetics for ammonia/hydrogen (NH 3 /H 2 ) combustion have advanced significantly in the recent decades, how well they predict nitric oxide (NO) formation has not been thoroughly examined. To this end, this paper comprehensively assesses the existing reaction kinetics for NO formation in NH 3 /H 2 /air flames through comparisons between their predictions and m
