Simultaneous Measurements of Multiphase Aerodynamics and Surface Hydrodynamics (SMMASH)
Abstract
Surface ships produce many important multiphase flows that are important for naval applications, including air bubbles entrained by, ship wake, spray droplets generated by bursting bubbles and wind gusts, and ice deposition and accumulation due to super-cooled liq,uid droplets impinging on marine platforms. Although experimental methods developed for single-phase fluid dynamics have advanced si,gnificantly in spatial and temporal resolution, these tools have limited capability when it comes to capturing the complex two-phase, interactions that involve poly-dispersed and sometimes deformable second phase. It is the goal of the proposed work to develop a co,mprehensive diagnostic method that involves three subsystems to track a high-concentration of poly-dispersed bubbles, droplets, or i,ce particles simultaneously with their surrounding turbulence in 3D. The developed system will assist an ongoing project by providin,g a better resolution in benchmarking datasets and unveil the key multiphase flow physics in the ship turbulent bubbly wake.
