Research Projects

Cold spray additive manufacturing

  1. The influence of turbulence on particle dispersion is investigated in a low-pressure cold spray system. Smaller particles are found to disperse more widely and are more likely to escape without being deposited.

Wildfire

  1. The transport of an idealized firebrand is examined in this study. The findings indicate that the time-varying temperature of the smoldering firebrand affects the ember's trajectory.

Sound mitigation using splitter plates

  1. Mitigation of aerodynamic sound generated by flow over a circular cylinder has been studied. Direct numerical simulation (DNS) shows that a sound reduction of up to 21 dB is achievable with a simple arrangement of splitter plates.

  2. Splitter plates significantly alter the downstream flow dynamics, resulting in weaker vortex interactions and, consequently, reduced sound generation.
