On the interaction of buoyant plumes and gaps with canopy mixing layers
Abstract/Contents
- Abstract
- Canopy mixing layers, as found in many environmental systems, quite significantly alter the local flow and turbulence fields. They also give rise to coherent structures that have a strong influence on the mixing and transport of momentum, turbulence, mass and heat in the system. Through experimental work with model vegetative canopies, this dissertation investigated systems in which the canopy mixing layers compete with other non-negligible processes. The first two topics are on canopies that are interrupted by gaps and trailing edges. The competing processes that alter the canopy mixing layer in gaps and edges are those related to flow expansion, reattachment, wake development, and boundary layer dynamics. The third topic looks at the interaction between canopy mixing layers and plume dynamics. The goal was to assess how canopy induced turbulence can impact the trajectory and behavior of hot buoyant plumes. All of these competing processes were studied to better understand the role of canopy dynamics in various environmental settings, most notably in wildfire spread. We connected our experimental work to looking into how mixing layer dynamics may alter the dynamics that is observed within fuel breaks, as well as wildfire plumes.
