High-Speed Thermal Imaging of Disk-shaped Firebrands in a Wind Tunnel
Charles Callahan, Erick Gatica, Sean Coburn +6
The transport and temperature-time history of disk-shaped firebrands was studied with high-speed thermal imaging in a wind tunnel. One millimeter diameter wooden disks were ignited…
WindCline: Sloping Wind Tunnel for Characterizing Flame Behavior Under Variable Inclines and Wind Conditions
Amanda S. Makowiecki, Sean C. Coburn, Samantha Sheppard +15
Developing accurate computational models of wildfire dynamics is increasingly important due to the substantial and expanding negative impacts of wildfire events on human health, in…
Assessing diffusion model impacts on enstrophy and flame structure in turbulent lean premixed flames
Aaron J. Fillo, Peter E. Hamlington, Kyle E. Niemeyer
Diffusive transport of mass occurs at small scales in turbulent premixed flames. As a result, multicomponent mass diffusion, which is often neglected in direct numerical simulation…
Efficient Simulations of Propagating Flames Using Adaptive Mesh Refinement
Caelan Lapointe, Nicholas T. Wimer, Jeffrey F. Glusman +5
Wildland fires are complex multi-physics problems that span wide spatial scale ranges. Capturing this complexity in computationally affordable numerical simulations for process stu…
Parameter Estimation for RANS Models Using Approximate Bayesian Computation
Olga A. Doronina, Scott M. Murman, Peter E. Hamlington
We use approximate Bayesian computation (ABC) to estimate unknown parameter values, as well as their uncertainties, in Reynolds-averaged Navier-Stokes (RANS) simulations of turbule…
Particle Pair Dispersion and Eddy Diffusivity in a High-Speed Premixed Flame
Ryan Darragh, Colin A. Z. Towery, Alexei Y. Poludnenko +1
Turbulent mixing is a physical process of fundamental importance in high-speed premixed flames. This mixing results in enhanced transport of temperature and chemical scalars, leadi…
