Shock-Tube Measurements of the Vibration-Vibration Energy Exchange Probability for the CO-N2 System
Abstract
A shock-tube study was carried out to measure the vibration-vibration energy exchange probability, P(N2, CO), in N2/CO/Ar mixtures. It was determined that at a temperature of about 4000K, the measured probability, P(N2, CO) is about 0.008, agrees fairly well with the theoretical prediction of Schwartz, Slawsky, and Herzfeld (SSH), but that with decreasing temperature the measured probability falls considerably below the SSH theory prediction. The experimental results also demonstrate that over the temperature range 2000-4000K, argon and nitrogen are about equally efficient as translation-vibration collision partners for vibrational relaxation of CO, whereas, argon is between 2 and 3 times less efficient than N2 for vibrational relaxation of N2 molecules.
