MUQOVIMATI GIDRODINAMIKI

MUQOVIMATI GIDRODINAMIKI (az arabi  va gidrodinamika), aksuttasirest, ki moe ba harakati jismi darunii on merasonad va muqobilatest, ki devorhoi gulbavu kanalho ba harakati moe nishon medihand. Dar surati andaruni seli moe (gaz) budani jismi sokin va yo, baraks, hangomi dar muhiti sokii harakat kardani jism Muqovimati gidrodinamiki ba pro-eksiyai vektori asosii hamai quvvahoi ba jism tasirkunanda bar samti harakat barobar ast va chunin ifoda karda meshavad:

X = Skh ‘J- S,

in jo r — zichii muhit, v — surat, S — masohati ba jismi mazkur (masalan, baroi samolyot — sathi bolho) khos, Skh — koeffisient bechenak. Skh ba shakli jism, mavqei vay nisbat ba samti harakat va adadhoi monandi vobasta ast. Muqovimati gidrodinamiki bo tasiri fishor va quvvai soish ba amal meoyad. Formulahoe mavjudand, ki az rgi onho Muqovimati gidrodinamikiro baroi jarayonhoi laminari va turbulenti hisob kardan mumkin ast.

Muqovimati gidrodinamikiro ba muqovimathoi kh a t t i, ki ba tufayli gizlati moe paydo meshavandu dar tamomi tuli qismi romtkhattai gqlba yo kanal tasir mekunand va muqovimathoi m a h a l l i, ki dar joyhoi tagyir-yobii qimat va samti surati jarayon (dar ventilho, jumakho, zonuho, sedahanho, diafragmaho, diffuzorho va gayra) ba amal meoyand, chudo mekunand.

Durust muayyan kardani buzurgiya Muqovimati gidrodinamiki  baroi tartib dodani loiha va sokhtmoni inshoot, jihoz va apparathoi gunogun (inshoothoi gidrotekhniki tajhizoti turbivi, apparathoi sofkorihoi havovu gaz, shabakahoi gaz, neft va ob, muharrikho, kompressorho, nasosho va gayra) ahamiyati kalon dorad.
