Crowd Surveillance and Fluid Dynamics
Video monitoring of large crowds is important for reasons of safety and security. But human monitoring can miss critical events. Because the movement of people in a crowd is very similar to the motion of particles in a moving fluid mathematical techniques can be used to convert video images into pixels (particles) and those particles tracked to identify trajectories. Trajectories that don’t match the expected fluid behavior can then be identified for additional scrutiny.

CFD Researcher Receives SWE Achievement Award
Prof. Cristina Amon from the University of Toronto recently received the Society of Women Engineers 2011 Achievement Award for her work in fluid mechanics and her commitment to gender diversity in engineering. Prof. Amon developed CFD methods for solving thermal design problems subject to multiple constraints. In her current role as Dean of Faculty she believes it to be more important than ever to ensure that women engineers are able to help solve the world’s challenges.

CFD is Changing Cycling
The folks at FLO Cycling firmly believe that CFD aided design is the way of the future. In this interview with CD-adapco’s Bill Clark they explore why that should be so. At one point in the interview Clark is quoted “In the past, these types of tools (CFD, FEA, CAD) were reserved for engineers with graduate degrees or people with masochistic tendencies.” [Emphasis mine.] I like to believe that mesh generation is the last great frontier for masochists.
