High Frequency, Time-Resolved Digital Particle Image Velocimetry System for Polydispersed Multi-Phase Flows

We propose to capitalize on the success of the Phase-I effort and develop a unique next generation three-dimensional DPIV system with the capability to resolve quantitatively with sub-pixel accuracy, both velocity and size of poly-dispersed multi- phase flows. This system is going to be unique compared with existing commercial systems in several aspects. Specifically, there is no commercially available PDIV system that: 1) delivers KHz time-resolution measurements 2) integrates a dynamically adaptive methodology with particle-tracking schemes, resolving the global three-dimensional velocities in a multi-phase flow with high accuracy (sub-pixel) and enhanced spatial resolution 3) resolves the size and shape of a dispersed phase simultaneously with the velocity measurements. The proposed system will deliver all of the above becoming an equivalent of a combined DPIV, LDA and PDA in one competitively priced package with the flexibility to address different fluid mechanics problems.The success of Phase-I, the unique features of the proposed system, the innovative task identified for Phase-II, the assembly of an experience team to carry out the effort, combined with the fact that the most prominent fluid diagnostics company worldwide will be marketing the system almost guarantees the success of the proposed project.
