Abstract : Flow through a contraction nozzle used as an inflow geometry for in-vitro vocal tract replicas mounted in an experimental flow facility is studied for low to moderate Reynolds numbers. The flow is characterised experimentally by hot-wire anemometry at the nozzle exit. The estimated boundary layer characteristics are used to validate Thwaites boundary layer solutions with the aid of universal functions for the shape and skin friction parameters.

Keywords : instrumentation contraction nozzle flow speech production boundary layer
