Tātai Hiringa Wai Whakatairanga mo te Rererangi Wai Whakatairanga Ake

Kupu Whakataki

Ka tuhia e tenei purongo te tātaritanga o te hihiko wai (CFD) i mahia i runga i te rerenga wai Circulator matatau i te paemahana me te pehanga o te US (STP).

Whāinga

Ka whakatauhia e tenei purongo te rerekeetanga whaihuatanga i waenga i te whakahokinga wai paerewa me te rerenga wai Circulator matatau i hangaia e Advanced Space-age Systems & Engineering Technologies - ASSET. Hei whakamutunga, e hiahia ana matou ki te whakaatu i nga moni penapena utu nui ka riro mai i te panui whakamiharo o te reeti wai Circulator matatau.

Hōputu Pūrongo

Ka whakaatuhia e tenei purongo nga papa tātaritanga hohonu me nga korero i whakaahuahia i roto i te whaainga.

Te huarahi tātari

Ko tenei waahanga e whakarārangihia ana te huarahi tātari i mahia. I whakatauirahia he whakatauira pangarau o te puna wai ki tonu i te wai kotahi. Ko te huarahi tātari ko te tatau tuatahi i te whaihuatanga o te hokinga mai o te wai puna ma te ine i te nui o te mata o te pakitara poka wai ka taea te makuku. Ka whakatauritea e matou tenei uara ki te waahi pakitara poka wai kua tatauhia ka makuku te rere wai Circulator matatau.

Ko te hokinga wai o te puna kaukau ka kiia kia heke ki raro o te puna. Ma tenei ara, ka whakaitihia nga paanga o te kaha. Katahi ka hangaia he maareti-mata o te tere wai e rite ana ki te 0.2 m/s. Ko te whakaaro ko te tere o te wai i raro i tenei uara ka kore e whai hua te makuku o te pakitara puna.

Ma te whakamahi i nga taputapu CAD paerewa, ka tatauhia te waahi pakitara i makuku i te hokinga mai o te puna kaukau. Ko te roa me te whanui o te waahi pakitara makuku e whakaatuhia ana i nga whika 1 me te 2. Ko te roa o te 93.8" i te whanui o te 25.9" ka homai he 8.44 putu tapawha o te waahi maku mo te hokinga mai o te puna kaukau ki te whakaaro tatou he tauira whakamararatanga tapatoru mo te wai.

Ka tuhia e te jet wai Circulator matatau he pewa me te 93.8 inihi te whanui. Mena ka whakaarohia e tatou he waahi iti o te porowhita hei utu mo te haurua o te porowhita kei te toro atu te rere wai Circulator matatau, ka taea e tatou te tatau i te waahi makuku mo te rerenga wai Circulator matatau penei:

Rohe mākū (Wāhi Kōpaki) = π r2/1.5 = π 93.82/(1.5 X 144) = 128 pūrua tapawhā.

Nga Whakamutunga tātaritanga

Ma te tango i te ōwehenga o nga waahi e rua ka taea e taatau te tatau i te rereketanga o te whaihuatanga i waenga i te hokinga wai paerewa me te rerenga wai Circulator matatau.

Ōwehenga: Rererere wai Porowhita Ake (Whahanga Mata) / Whakahoki Puna Paerewa (Whahanga Mata) = 128 / 8.44 = 15.17

Ko te jet wai Circulator matatau he 1500 % ake te whai hua atu i te hokinga wai kaukau paerewa i runga i te waahi pakitara poka wai i makukuhia e te jet.

Ka tuhia e tenei purongo te tātaritanga o te hihiko wai (CFD) i mahia i runga i te rerenga wai Circulator matatau i te paemahana me te pehanga o te US (STP). I whakatauhia ano hoki te rereketanga o te whaihuatanga i waenga i te hokinga wai paerewa me te rerenga wai Circulator matatau i hangaia e Advanced Space-age Systems & Engineering Technologies - ASSET, he 1500% te pai ake i te hokinga wai puna wai.
