Sare u leh Helita Hantiya iyo Jiritaanka Dahsoon
Sareega dhulka qaab la'a ee HDPE ah ee loo isticmaalo nidaamka bixinidka bartamaha ay leedahay awood dheer oo ku tiil badan iyadoo lacagta sare u dhaxliyey hooska sareegeed ee ka dhalanaya xad-dhaadhitaanka qalabka iyo kordhinta awoodka. Xagga ka sosaaraha sareegeedka wanaagsan waxa uu si degdeg ah u yeeshaa Manning's 0.012, ka wayn marka loo eego sarxanta, dhulka la'aqaabka metalka ah ama dhulka la'aqaabka taano. Wanaagsigaas sareegeedka waxa uu si toos ah u kordhiyaa awoodka bixintaa, sidoo kale midhaha yarreeka awood kala yihiin kala duwan. Wanaagsiga saynarka waxa uu kordhiyaa awoodka bixinta, si ay midhaha yarreeka ugu hor yimaadaan jumladda isku raacaya, ka buuxiya dookhaasha iyo khaladka lagu samaynayo intuu awoodka samatabbaxa. Hooska sareegeedka wanaagsan ka hortaa kororinteeda iyo qalabka aan la isticmaalin oo ka soo baxsan in kala duwan, sidoo kale awoodka bixinta buuxda ay ku jiraan mudda caawinaad. Saynarka laga saaro waxa loo heli karaa heerka bixinta yar, sababtoo ah xad-dhaadhitaanka ka hooseeya, sidoo kale qalabka la wareegsaday ay ka saarto si xun intuu shaqada normal ahaan guurdo. Sifada saynarka ay ku jiraan mudda dheer sababtoo ah polyethylene ma guursan, ma dhalaalin ama ma gudban, sida metalka ama sarxantaka. Tijaabiyaal laboratoorka ay muujiyeen in awoodka bixinta ha ka sameyn karin intii kaleba, sidoo kale awood dheer si degdeg ah u kordhiyaa. Sareega dhulka qaab la'a ee HDPE ah ee loo isticmaalo nidaamka bixinidka bartamaha ay ka hortaa xad-dhaadhitaanka ku jira isdhexgalka, sababtoo ah hooska sareegeedka wanaagsan ay socotaa si toos ah meelaha isku darka. Ka xad-dhaadhitaanka iyo ka qaybinta awoodka waxa loo kasta si fudud marka loo eego noocahan habdhanka, sababtoo ah qaabka ay go'aami karaan talleef xooggan oo aan xagga ka sosaaraha hooska ugu daran. Sifada saynarka wanaagsan waxay kordhiyaa saynarka gravity-flow si ay u shaqeeyaan si wanaagsan heerka yar, ka buuxiya dookhaasha iyo fududaysid intuu la samaynayo meelaha baroor. Modeliga computational fluid dynamics (CFD) ay muujineen inay leedahay awood wanaagsan oo kordhiyaa khaladka lagu samaynayo adigaba midhaha yarreeka iyo wanaagsanidka nidaamka.
