Combined probe for simultaneous measurement of velocity, temperature, and pressure
摘要
A novel combined probe was developed for the simultaneous measurement of velocity, temperature, and pressure. The combined probe consists of hot-wire probe, cold-wire probe, and pressure probe. The probes were arranged along the streamwise direction and the spatial disagreement of the measurement locations was corrected based on time-space conversion of the measured signals. The performance of the combined probe was verified in a heated plane jet. The statistical characteristics of velocity, temperature, and pressure field showed that the present combined probe could correctly measure the flow field when the mean streamwise velocity was large. Finally, all of the terms in the turbulent heat flux equation were evaluated using the combined probe. The confidence of the combined probe for the simultaneous measurement of velocity, temperature, and pressure was strongly supported by the turbulent heat flux budget.
