Examination of Wildland Fire Spread at Small Scales Using Direct Numerical Simulations and Frequency Comb Laser Diagnostics
Abstract
The primary objective of this project was to understand and characterize wildland fire spread at small scales (roughly 1m - 1mm) using high fidelity direct and large eddy simulations (DNS and LES, respectively) with reduced chemical kinetic mechanisms calibrated using data from frequency comb laser diagnostics (FCLD). Specific objectives of this project were to (i) Understand and characterize wildland fire spread at scales from roughly 1m to below 1mm using DNS and LES to directly resolve relevant fluid and chemical processes. (ii) Develop and calibrate reduced chemical kinetics mechanisms for the pyrolysis, ignition, and combustion of wildland fuels. (iii) Use frequency comb laser diagnostics to study wildland fire spread at small scales by providing data for the calibration of reduced chemical mechanisms and for simulation validation. (iv) Use insights from the computations and experiments to perform improved simulations of wildland fire spread at landscape scales.
