We have been promoting the use of Computational Fluid Dynamics (CFD) in the development of prop guards for a long time. It’s been on our Help Us page for several years, we mentioned CFD in our January 2009 post on a Propeller Guard With Reduced Drag, and just a few days ago we briefly discussed the use of CFD in our The Emperor Has No Boat: SUNY Propeller Guard Testing post. In addition, our efforts to encourage engineering and design students working on student projects, thesis, and dissertations to consider studying propeller guards has a student that looks like he is going to be working at least in part, on propeller guard CFD.
Computational Fluid Dynamics (CFD) is a natural fit for propeller guard design. It allows sorting through the design variables to optimize the propeller guards to reduce drag, minimize their impact on boat handling issues, make sure cavitation issues do not cause a problem, and even test the interaction between propeller guards and humans (human factors issues of being struck by a guard, being entrapped, or being pulled into a recreational boat propeller).
