(DURIP) ACQUISITION OF A LASER SYSTEM FOR A TOMOGRAPHIC PARTICLE IMAGE VELOCIMETRY AND A MASS FLOW CONTROL SYSTEM FOR FLUID-STRUCTURE INTERACTION INVESTIGATION OF ACTIVE BLOWING ON DEFORMABLE SURFACES
Abstract
This project requests support for the acquisition of a laser and a laser light arm to upgrade and improve an existing Volumetric Particle Image Velocimetry (VPIV) system, a workstation for computational fluid dynamics (CFD) analysis and equipment for a mass flow control system. The system will provide the ability to carry out volumetric velocimetry measurements, which are a key facilitator for investigating and understanding 3D unsteady turbulent flows. It will create a unique opportunity for the PI to develop transformative research and achieve his long term research goal, which is to establish a framework that associates a wing’s active surface deformation and blowing intensity with the near wall coherent structures to design active flow control (AFC) systems that manipulate flow structures for efficient boundary layer control. AFC technologies have a wide range of uses from separation control to lift augmentation and flight control? however, the exploitation of such technologies has been limited mainly due to the mass flow requirements. There is an increasing interest in aerospace research for numerical modeling of deformable control surfaces to predict flow behavior in highly turbulent flow environments to improve fixed wing aircraft performance during flight. CFD can provide insight into the physics of 3D complex and turbulent flow structures, but accurate modeling of the flow depends on experimental validation, which requires a nonintrusive measurement technique such as PIV testing. The proposed laser will advance the existing VPIV system and will enable the study of fundamental advances in fluid dynamics, which could yield insights into flow characterization around deformable surfaces. In addition, funds are requested to purchase equipment for a compressed air system with a dual channel consisting of two independently controllable air pressure lines for AFC testing and a workstation for CFD analysis.
