The study of particle-laden turbulent flows is important in order to fully understand important processes applicable to everyday life. The motion of ash after volcanic erruptions, radioactive particles suspended in the air after a nuclear accident, and air-borne pollutants are just a few examples of particle transport which effect everyone's local and global environment. Additionally, the design of various pieces of equipment such as the fuel injection system in motorized vehicles can be optimized with a fuller understanding of the turbulent flows within. Understanding the physics that embodies these processes offers an opportunity to improve life by improving safety, the environment, and the design of equipment.
Applications exist beyond the planet as well.
Future missions to Mars will greatly benefit from advanced knowledge of the behavior of the dust which sculpts the planet. Not only is it essential for understanding geological features on the planet, but it is also important in planning manned missions which could be negatively effected by windblown materials. Tatical Approach At Tufts University a three-tiered approach has been chosen to study the motion of particles in a turbulent flow. The three components work separately but are complimentary and help confirm the validity of the various methods. The particle and flow characteristics studied in the various methods both overlap and operate in different ranges in order to increase the range of characteristics studied while maintaining a baseline for result confirmation.
