Krinkels, M.C.J.M. Heemskerk, J.F. Delil, A.A.M. Institution National Aerospace Laboratory NLR Date 1989-10-10 Abstract Acoustic techniques for the tracking of a tracer particle in a liquid have been detailed for a specific problem. The liquid is a molten metal in a crucible in a precision furnace; the tracer particle could be a bubble. The acoustic hardware is exterior to the furnace and is coupled to the sample via a small number of liquid-filled waveguides that terminate at an endface of the cylindrical crucible. The liquid in the waveguide could be different from the sample liquid. This concept allows to decouple the thermal and accessibility problems from the acoustic signal generation and reception equipment. The relevant operational modes and required hardware provisions are discussed. The further development of the concept is to be tested on a scaled-up model of the configuration that is transparent and so allows optical diagnosis. A sketch design of this breadboard is elaborated.
