Sareyn Sareyn Weyn iyo Hormuudinta Hidaadda
Astaanta xidhidda ee istaajinta hdpe krah pipe waxay muujiinaysaa dhaawacyo muddo dheer oo leh kuwa ugu horreeya astaanta koronto, taasoo abuuraaya faa'iidooyinka aasaaska ah ee korontada dhammaan muddada korontada. Dhexdhexda gacmahood buuxda waxay haysta koofishentka Manning oo 0.009-0.012, ka hooseeya wadararta ama badhanka la dhisiyey qabeelka, taasoo imanaya in korontada loo baahan yahay ka qaadasho iyo korontada si degdeg ah loo sameeyo qabiilaha isku mid ah. Sidaas daraaddeed astaanta xidhidda waxay noqonaysaa muhiimka ah korontada dhulka ah, halkaas oo korontada loo amraya in ay ilaaliyaan socodka iyo in ay saamaysaan kala jebin kacaanka iyo in ay keeno shaqada saafin. Dhexdhexda gacmahood buuxda waxay ku tiisaysaa illow lisan, micnaha ma uusan kala duwan maalin kala duwan sida meelaha loo yaqaan in ay kala duwan tahay sababtoo ah in ay kalaggaan, in ay dhalaan ama in ay dhaliyaan nidaamka biyaha, taasoo marwaliba ku saamaysaa awoodda nidaamka iyo kala weynsada khaladarka. Qaab-dhismeedka saldhigga ah waxay hubiysaa in ay leedahay heer gaar ah oo leh koronto, taasoo abuuraaya shakhsiga korontada si loogu talagalay iyadoo aan lahayn kala duwanaansho lagu arko qabiilaha loo daabacay ama loo dhiso. Isku daynashadii korontada waxay ilaaliyaan dhexdhexda gacmahood buuxda, taasoo saamaysaa in ay kala duwan tahay kala duwanaansho lagu samayn karaa khaladarka iyo in ay saamaysaan kala jebin kacaanka korontada joogto ah. Wixii la tijaabisay fluid dynamics (CFD) waxay muujiyaan in istaajinta hdpe krah pipe ay leedahay astaanta laminar flow qaniinyada ka hooseeya, taasoo saamaysaa in ay kala duwan tahay kala duwanaansho, haddaba ay ilaaliyaan socodka loo baahan yahay in ay saafin kacaanka iyo in ay kala duwan tahay in ay kala jebin kacaanka. Awoodda kiimikiga ah ayaa ilaalinta in dhexdhexda gacmahood buuxda ka dhici kara in ay kalaggaan ama in ay dhaliyaan nidaamka biyaha, taasoo ilaaliya astaanta xidhidda dhammaan muddada loo dhisay in ay kala duwan tahay awoodda. Tijaabada korontada waxay muujiyaan in ay leedahay awoodda si degdeg ah muddo dheer, taasoo allabari karta in awoodda nidaamka ay yihiin si cad in ay kordhin karaan iyo in ay dhisin karaan. Dhexdhexda gacmahood buuxda waxayna caawinaan tijaabada iyo shaqada saafin marka loo baahan yahay, taasoo saamaysaa shaqada saafin iyo khaladarka la xidhan, dib u eeg meelaha loo yaqaan in ay kala duwan tahay. Kuwaas astaanta xidhidda waxay ka dhigantahay khaladarka muddo dheer, sababtoo ah in ay kala duwan tahay khasaaraha iyo shaqada saafin, taasoo kala sarraysa muddada loo isticmaalo, taasoo kala weynsada awoodda nidaamka, haddaba ay kala duwan tahay shaqooyinka la xidhan nidaamka xooggan.
