Research abstract
THE PROBLEM OF GAS DYNAMIC FLOW PROPERTY MEASUREMENT IN PARTICLE LADEN FLOWS IS ADDRESSED VIA AN ADVANCED NUMERICAL MODEL SIMULATION STUDY OF PRESSURE GAUGE RESPONSE. THE APPROACH UTILIZES A HIGH-ORDER ACCURATE NUMERICAL SOLUTION TECHNIQUE FOR TURBULENT TWO-PHASE FLOWS. GAUGES OF EXISTING DESIGN SUCH AS THE GREG/SNOB GAUGES WILL BE ANALYZED OVER A RANGE OF CLEAN AND DUSTY AIRBLAST FLOW ENVIRONMENTS AND GAUGE RESPONSE WILL BE COMPARED TO PRESCRIBED DUSTY FLOW PROPERTIES. THE EFFECT OF DESIGN PERTURBATIONS, LEADING TO IMPROVED FIDELITY OF GAUGE RESPONSE, WILL ALSO BE EXAMINED. FINALLY A PRELIMINARY PROGRAM PLAN WILL BE DEVELOPED FOR AN EXTENSIVE ANALYTICAL AND EXPERIMENTAL PROGRAM TO OPTIMIZE GAUGE DESIGN.
