A theoretical analysis was made on the behaviour of the free molecule impact tube pressure probe with respect to the gas-surface interaciton effent at the inlet portion of the tube wall. The solution was expressed in terms of four parameters representing the tube geometry, free stream velocity, tube angle of attack, and surface interaction property and was an extention of the theories of Harris Patterson, deLeeuw, and others who assumed that the colliding molecules accommodate completely to the wall. Experimental measurements were conducted on free jet flow for angles of attack up to 60 deg. The flow speed ratio was sufficiently large. Nitrogen, argon and helium were supplied as test gases, with the stagnation temperature varied from 300 deg K to 1000 deg K. In order to obtain the high molecular speed, a binary mixture technique was introduced, that is, 7% helium was added to nitrogen and/or argon. When the stagnation temperature was not high, the measured values agree with the theories by Harris et al. But with our increasing mean molecular speed, these values shifted to theoretical curves corresponding to the slightly smaller values of the interaciton parameter. This was dhue ot the specular reflextion molecule numerical increase with the increasing molecular velocity. In a theoretical comparison the interaction parameter or was found to vary from 1.0 to 0.8. The results of subsonic tests by a rotating arm apparatus was also described briefly. |
