Abstract:

MEASUREMENT OF VELOCITY FIELDS AND FLOW RATES IS OF PRIME IMPORTANCE IN MANY AREAS OF INDUSTRY AND FLUID DYNAMICS RESEARCH. THE RESEARCH PROPOSED HEREIN WOULD RESULT IN A NONINTRUSIVE MEANS OF DETERMINING THE MAGNITUDE AND DIRECTION OF VELOCITY AND THE CORRESPONDING FLOW RATES BY THE USE OF LASER TOMOGRAPHY. LASER TOMOGRAPHY MAKES USE OF THE FACT THAT, FOR PROPERLY TUNED LASERS, THE DECAY OF LASER BEAM INTENSITY (EXTINCTION) DEPENDS UPON THE VELOCITY OF THE FLUID THROUGH WHICH IT PASSES. IN THE CASE OF AXISYMMETRIC FLOWS, SUCH AS IN A PIPE, THE FLOW RATE CAN BE DETERMINED FROM THE ATTENUATION OF A SINGLE BEAM PASSING THROUGH THE FLOW. THE DETAILS OF THE VELOCITY FIELD FOR SUCH A FLOW CAN BE OBTAINED WITH A MULTIBEAM ARRANGEMENT ACROSS THE FLOW. THE METHOD CAN ALSO BE EXTENDED TO COMPLEXTHREE-DIMENSIONAL FLOWS, WHEREIN A MATRIX OF LASER BEAMS COULD BE USED. THE OBJECTIVE OF THE PROPOSED RESEARCH IS TODEVELOP A PRACTICAL LASER TOMOGRAPHY DEVICE FOR THE MEASUREMENT OF VELOCITIES AND FLOW RATES IN FLOWFIELDS OF BOTH FUNDAMENTAL AND PRACTICAL IMPORTANCE.
