Nyob rau hauv thaum ntxov impulse turbines xws li Laval turbine thiab recoil turbines xws li Parsons turbine, lub impeller yog cov ntsiab lus tseem ceeb, thiab nws cov kev ua tau zoo muaj feem xyuam rau qhov nyuaj ntawm cov qauv hniav.
Impeller tsim tau dhau los ntawm kev hloov pauv los ntawm kev cia siab rau cov qauv qauv thiab phau ntawv kos duab los qhia txog cov thev naus laus zis thev naus laus zis xws li kev suav cov dej dynamics thiab cov qauv kev ua haujlwm.
Thaum ntxov xyoo 1950, Wu Zhonghua tau tsim peb qhov - qhov kev xav ntawm qhov dej ntws ntawm turbomachinery (S1, S2 ntws nto txoj kev xav), uas tau siv rau hauv kev tsim cov turbines rau peb lub Gorges Dam qhov project hauv kuv lub tebchaws. [10] Niaj hnub nimno aerospace thiab lwm yam kev lag luam siv peb - qhov ntev ntws nto tsim rau impellers, thiab los ntawm kev simulation optimization ntawm ntws channel, hydraulic efficiency yog ho txhim khu kev qha piv nrog empirical tsim (xws li, ntau tshaj 30%).
Tam sim no, impeller thev naus laus zis tab tom hloov pauv mus rau ntsuab thiab hluav taws xob, suav nrog kev txhim kho qis - suab nrov thiab qis- kev tsim qauv siv, thiab kev tshawb nrhiav cov ntaub ntawv sib xyaw, hydrogen roj- sib xws impellers, thiab topology optimization technology raws li kev kawm tshuab.
