Notes:
Measurements were obtained in the Rensselaer transonic windtunnel with front and side sensors on block and domed configurations of hot-dome probes in the uniform freestream over the range Mach 0.42 to 0.82 and for pitch and yaw angles of up to 60 deg. Results are presented with two hot-dome probe configurations, a block probe and a domed probe, and quantify effects of probe geometry, angle sensitivity, and velocity up to transonic Mach numbers. Block probe showed turbulence generation in the vicinity of the hot-film sensors, probably associated with recirculating flow downstream of its sharp corners. The domed probe was designed with rounded front and side surfaces to realize benefits from aerodynamic contouring and effect reductions in blockage, probe interference, separation, and compressibility. The curved front sensor of the domed probe responded primarily to the normal component of cooling velocity, and this implies that the front sensor of domed probes can be used to obtain the magnitude of flow velocity. Responses of pitch and yaw sensors on the domed probe suggest angle calibrations similar to those for five-hole impact probes may be suitable for hot-dome probes.
