| Abstract: | Cyclopropane in argon mixtures was heated in a single-pulse shock tube, and syringes were used to withdraw samples from both the central gas slug and the gas adjacent to the tube walls. Differences were observed in the measured conversion, with larger conversion found in the center location. The discrepancy increased with increasing conversion, and the results indicate that boundary-layer effects can seriously affect the results of absolute single-pulse shock-tube studies when percent conversion is large. |
