Episode Nine: Just Blood Spatter
Just Blood Spatter
In episode nine of Just Science, funded by the National Institute of Justice’s Forensic Technology Center of Excellence [Award 2016-MU-BX-K110], we spoke with Dr. Marc Smith, from the Georgia Institute of Technology. Dr. Smith’s NIJ funded research in blood spatter has connected computational fluid dynamics with empirical studies to improve the understanding of blood spatter onto solid, slanted surfaces. His work looks at many variables, including droplet size, speed, surface roughness and wettability.
Marc K. Smith is a Professor of Mechanical Engineering at the Georgia Institute of Technology. He received his Ph.D. degree in Engineering Sciences and Applied Mathematics from Northwestern University in August 1982. After post-doctoral work at MIT, Department of Mathematics and Cambridge University, DAMTP, he joined the faculty of Johns Hopkins University in the Department of Mechanical Engineering. He moved to the G. W. Woodruff School of Mechanical Engineering at Georgia Tech in 1991. His research interests include interfacial fluid mechanics, boiling flows, droplet impact, and hydrodynamic stability, with particular emphasis on surface tension effects and surface-tension-driven flows. His recent work includes studies on the acoustic enhancement of boiling heat transfer and condensation for enhanced heating and cooling applications, and droplet impact during blood spatter for forensic applications. His teaching interests include fluid mechanics, thermodynamics, and numerical methods for engineers.
