This manuscript details the thermal design, analysis, and experimental characterization of a cooled aerodynamic probe to house sensitive instrumentation for diagnostics in high-enthalpy environments up to 𝑀1 = 6 and 𝑇01 = 1700 𝐾. The probe is cooled using an open cycle gaseous cooling jacket terminating in a pattern of backward oriented ejection holes. The cooling jacket has been sized using a 1D heat transfer model and requires a head pressure of 3 bar to satisfy the thermal limits of the stainless-steel walls (800 K) and enclosed instrumentation (315 K). The effusion cooling effectiveness of the probe is further characterized through a parametric study using 3D steady RANS simulations
from subsonic to high supersonic conditions. Experimental tests have been conducted in an underexpanded open jet at 𝑀1 = 1.07 and 𝑇01 = 370 K using “in-situ” calibrated Infrared thermography to resolve the conjugate cooling effectiveness of the probe across the effusion faces. Cooling patterns observed in the effusion faces in simulations at 𝑀1 = 6 are observed in the transonic test under similar pressure ratios, and the conjugate cooling effectiveness agrees with computational predictions.
