AN EXPERIMENTAL STUDY TO DETERMINE THE UTILITY OF STANDARD COMMERCIAL HOT-WIRE AND COATED WEDGE-SHAPED HOT-FILM PROBES FOR MEASUREMENT OF TURBULENCE IN WATER-CONTAMINATED AIR FLOWS

Abstract

Tests were made to determine the response of hot-wire and wedge- shaped coated hot-film probes to liquid water-contaminated air flow. It was found that conventional hot-wire probes are not suitable for turbulence measurements in such flows, while the hot-film probes are suitable in certain situations. Probe contamination by salt encrustation would prevent effective use of either sort if the contaminating water were saline.
