Task 1. Develop the necessary software for integrating the triples pulse algorithm into PIV Sleuth, an open source correlation based PIV interrogation software system (Christensen 2000) Deliverable: PIV Sleuth program containing an option for triple pulse image analysis. Task 2. Construct a three laser/three camera frame PIV system for testing the triple pulse method and software. Deliverable: Test bed for four different triple-pulse approaches: 1) 3 separate camera frames using 2 PIV cameras; 2) 2 camera frames using one PIV camera with double exposure of the second two pulses in the second frame; 3) second-order correlation analysis of images from 1) and 2); 4)third-order correlation analysis of images from 1) and 2). Task 3. Construct a test section for accelerating water flow and perform experiments in a converging nozzle flow having known acceleration field Deliverable: Proof of principle images for the triple pulse method, accuracy assessments for measurement of velocity and acceleration in a fluid, and operating procedures to optimize the algorithms used for the triple-pulse correlation analysis
