| titleOfInvention | A kind of above-critical state and the close flow measuring apparatus of gaseous hydrocarbon fuel and method |
| abstract | One above-critical state of the present invention and the close flow measuring apparatus of gaseous hydrocarbon fuel, including plural series connection sonic nozzle, described sonic nozzle includes waiting straight section, contraction section, constricted throat and expansion segment；The straight section that waits of the 1st sonic nozzle is connected with hydrocarbon fuel heating means exit；Each sonic nozzle all reaches the velocity of sound in throat.Measuring method comprises the following steps: one, fuel to be measured is heated to temperature and is about T o And it is passed through this device；Two, sonic nozzle m etc. measure its import pressure P ' on straight section m With temperature T ' m ；Three, fuel to be measured is calculated at sonic nozzle m import pressure P ' m With inlet temperature T ' m Close flow valuve under state: A m For sonic nozzle m throat opening area.Utilize these apparatus and method can accurately, above-critical state and gaseous hydrocarbon fuel reach the close stream under " being jammed " state under the measurement different conditions point of low cost. |
