Multiphysics Control of Spray Formation and Dispersion
Abstract
This proposal addresses the need to improve liquid sprays through active control in processes ofinterest to the Navy and DoD, both technological and environmental. It is proposed to developnovel and effective numerical algorithms in conjunction with experimental and simulationapproaches to impact spray control to the point where complete engineering solutions to spraycontrol are possible. Specifically, the proposing team will employ their leading expertise increating improved experimental characterization and real-time sensing for dense sprays, highfidelity numerical simulations of turbulent liquid-gas flows from first principles, and novel andeffective algorithms for adjoint-based unconstrained and constrained optimal control, and modelreduction to enable the tailoring of a spray to application-defined objectives using novel multiphysicsactuation. Jet-engine fuel injection sprays are the target application in which to wrap allthe fundamental advances created in this project around a unifying technological challenge. Inorder to demonstrate multi-physics control of fuel sprays, two emerging but proven multiphaseactuation strategies will be employed, namely acoustic and electrostatic forcing, in addition todirect pulsing of the flow rates at injection
