Dusty Shock Experiment Operational The first experiments were demonstrated with a new experimental capability involving the study of how a shock wave interacts with a dust layer. A new test section was designed and built to perform these tests behind incident shock waves in our existing 10.8-cm square shock tube. High-speed images of the dust layer after passage of the shock wave are obtained with a shadowgraph technique. The students on this project are Brandon Marks and Amira Chowdhury with funding from the Mary Kay O’Connor Process Safety Center.

Turbulent Flame Speed Rig Operational On December 8, 2012, the first experiments were performed in our new turbulent flame speed facility. This facility has been under design and characterization over the past two years and represents a significant advancement in our experimental capabilities. The turbulence is generated from 4, centrally located fans; the design is such that separate control over the turbulence intensity and length scale is possible. The lead researcher on this project is Sankar Ravi, and the first tests were performed with the help of Anibal Morones. Funding for this project comes from DOE-NETL, Alstom, Rolls-Royce, TEES, and the Turbomachinery Laboratory.
