| 摘要： | A computer-aided data acquisition system was utilized in the study of the effect of mass flow on exhaust stack eductor performance. Pressure and temperature data was acquired via a Hewlett Packard data scanner and a scanivalve was utilized to aid in pressure data acquisition. Verification runs were conducted on a previously tested model with known performance characteristics with favorable results. Model diffuser ring geometry was altered to enhance film cooling and avoid local hot spots noticed in previous research. Uptake Mach numbers were varied between 0.06 and 0.024. The eductor pumping coefficient was found to increase from 0.6 to 0.69 respectively. Shroud and diffuser ring temperatures varied slightly with Mach number, however temperatures noticed were lower than those reported earlier due to the increased performance of the eductor. |
