Kahe ka slurry Centrifugal Slurry i loko o ka impeller

I ka Slurry e hana ana i ka wai i ka wā e holo ai ka huila me nā ʻaoʻao nui i hui pū ʻia, i ka manawa like a mai ka impeller rotating i kēlā me kēia lele. ʻO ka wai me ka neʻe ʻana o ka impeller i kapa ʻia he neʻe pōʻai, ʻo ka helu kumu i kapa ʻia ʻo peripheral speed, hoʻohana ʻoe i ʻōlelo ai. ʻO ka wai mai ka impeller rotating i loko o waho kahe i kapa ʻia he neʻe pili, kona wikiwiki pili velocity, i hōʻike ʻia ma W. wai e pili ana i ka neʻe ʻana o ke kino pauma i ʻike ʻia ʻo ka neʻe holoʻokoʻa, ua kapa ʻia kona wikiwiki ʻo ka holo holoʻokoʻa, me ka V e hōʻike ana i ka wikiwiki loa V a ʻo u. e like me ka māmā holo pili o ka velocity vector a me W , ʻo ia hoʻi, V = u + W ʻO ka māmā holoʻokoʻa o ka impeller e hoʻokele ana i ka ʻaoʻao laina tangent circumferential wai, e like me ka hōʻike ʻana ma 2-1a); ʻO ka ʻaoʻao e pili ana i ka velocity pili o ka wai, ke kuhikuhi holoʻokoʻa o ka velocity velocity o ka circumferential kuhikuhi o ka hui pū ʻana a me ka wikiwiki pili, e like me ka mea i hōʻike ʻia - Kiʻi 2. Hiki ke hōʻike ʻia ka neʻe wai i loko o ka impeller ma ke kiʻi. ʻO ka pakuhi e hōʻike ana i ka wai i ka māmā holo impeller a me ke kuhikuhi o ka neʻe ʻana ua kapa ʻia ʻo ka triangle velocity. ʻO ka wai i loko o ka wikiwiki o ka impeller i kēlā me kēia kiko o ka huinakolu i hōʻike ʻia ma ke Kiʻi 2-2. Paʻa . I kekahi manawa,mea hana pahū slurryʻO ka mea maikaʻi loa ʻo ia ka impeller inlet a me waho o ke kahe kahe wai.

Ke ʻike ʻia ka nui o ka impeller, nā ʻāpana i hāʻawi ʻia, hiki ke hana ʻia ka impeller me ka triangle velocity inlet a me ka puka, i hiki ke nānā ʻia ka wai ma ka inlet impeller a me ka puka o ka moku kahe. I mea e hana ai i ka huinakolu velocity, ua hoʻoheheʻe ʻia ka māmā holoʻokoʻa i ʻelua ʻāpana velocity orthogonal: hoʻokahi ka wikiwiki kūpaʻa o ka velocity pōʻai, ua kapa ʻia ʻo ia ka wikiwiki axial, i hōʻike ʻia e Vm; ʻO kekahi ʻaoʻao ʻē aʻe e kūlike me ka māmā pōʻai o ka ʻāpana velocity, i kapa pinepine ʻia ʻo ia ka ʻāpana velocity circumferential, me ka ʻōlelo ʻana o Vm, i hōʻike ʻia ma ke Kiʻi 2-3.

Ma ka huinakolu velocity , ua hoikeia ka huina o ka velocity piha V ma waena o ka velocity u me kekahi huina i oleloia ma waena o ka mämä holo pö'ai o ka velocity pili w i hoike 'ia e u ma waena o β.
