INSTRUMENTATION FOR FLUID-FLUID TWO-PHASE SYSTEMS

THIS RESEARCH PROJECT UNDERTAKES TO DETERMINE THE LIGHT SCATTERING OF BUBBLES IN A MEDIUM WHEREIN THE REFRACTIVE INDEX OF THE SCATTERING MEDIUM IS LESS THAN THAT OF THE SURROUNDINGS. THE RESEARCH WILL FOCUS FIRST ON THE DEVELOPMENT OF APPROPRIATE SOFTWARE TO INCORPORATE INTO AN EXISTING INSTRUMENT TO DETERMINE THE SIZE AND VELOCITY OF THE BUBBLES TOGETHER WITH THEIR NUMBER DENSITY, MASS FLUX, AND VOID FRACTION, AND, SECOND, ON THE MEASUREMENT OF MONODISPERSE AND POLYDISPERSE DISTRIBUTION OF BUBBLES TO CALIBRATE THE INSTRUMENT AND TEST THE VALIDITY OF THE APPROACH. HIGH SPEED PHOTOGRAPHY WILL BE USED IN THE EXPERIMENTAL PHASE AS A SECOND MEANS OF VALIDATION. AN ALGORITHM TO VERIFY THE SPHEROIDAL SHAPE OF THE SCATTERERS WILL ALSO BE INCORPORATED.
