Heat transfer characteristics of small configuration hot-wires in low Reynolds number subsonic and
supersonic air flows

Abstract:
Heat loss measurements from 20 gin. and 50 gin. hot-wires with aspect ratios between 95 and 420 were
obtained in air flows in the range 0<3.0 and 0.1 < 10. Measurements in compressible flows were
obtained in the throat region and test section of the Montana State University Supersonic Wind Tunnel.
An alternative theory suggested by Demetriades is used for determination of the Nusselt number and
recovery temperature of the hot-wire. The heat loss measurements were corrected for conductive end
losses to the hot-wire supports and compared to the correlations of Dewey and Collis and Williams.
The results indicate that flow conditions in the vicinity of lower aspect ratio wires are altered so that
heat loss from the wire may not be correctly determined from theory. High aspect ratio hot-wires
converge toward Dewey's correlation for M>2; however, similar hot-wires may behave differently and
individual flow calibration for each wire is necessary for quantitative flow measurements. Nusseit
number measurements in low velocity flow fall below the correlation of Collis and Williams by 5 to 20
percent. Recovery temperature measurements in M=3 flows vary considerably (30 %) for probes under
similar flow conditions and show no distinct dependence on either SI/d or Kn. Recovery temperatures
of the hot-wires in low velocity flows indicated the stagnation temperature w ithin 2 .5 %. HEAT TRANSFER CHARACTERISTICS OF SMALL CONFIGURATION HOT-WIRES
