As an important branch of combustion, spray combustion is widely used in industrial fields. Developing efficient and high-fidelity numerical models has important significance in simulating multi-component reacting flows, which is the focus of the current dissertation. The newly-developed spray flamelet approach combined with the multi-component fuel in the LES framework performs satisfactorily when applied to the two-phase turbulent combustion. The inclusion of the dispersed phase in the tabulation allows direct consideration of the fuel impact. The present work has demonstrated that the complex nature of multi-components and the multiple combustion regimes in the two-phase combustion can be directly included in the spray flamelet approach, which can provide new insights into the complex turbulent spray combustion.
Ran Yi received her B.S and M.S. degrees in Aerospace Propulsion Theory and Engineering from Beihang University in 2015 and 2018, respectively. She is currently a Ph.D. candidate at UM-SJTU Joint Institute, Shanghai Jiao Tong University. Her research interest is focused on the numerical modeling of multi-component spray combustion.
