DEVELOPMENT OF THERMOCOUPLE-TYPE TOTAL TEMPERATURE PROBES IN THE HYPERSONIC FLOW REGIME
Abstract
An experimental study to develop the criterion necessary to construct a miniature shielded thermocouple total temperature probe suitable for application in the hypersonic flow regime. Particular emphasis was given to the effect that internal velocity and thermocouple junction location relative to the shield entrance had on temperature measurements. An error analysis resulting from heat transfer phenomenon was made. The measured total temperature-to- tunnel stilling chamber temperature ratio was correlated in terms of the entrance flow length-to-probe length ratio. Over the range of parameters investigated both the optimum length-to-diameter and the optimum entrance-to- vent area ratios were found to be two. The entrance flow length-to-probe length ratios effectively correlated the data from probes of a given internal diameter.
