Cavitation firfircoon gudaha duritaanka naaftada waxqabadka sare - tijaabo iyo baaritaanka CFD (qayb 4)
Marka la soo koobo:
Sawir-qaadista xawaaraha sare ee cavitation gudaha marinka kontoroolka ayaa shaaca ka qaaday saameyn garaacis ah oo aan lagu arag daraasadihii hore.Dalool weyn oo faaruq ah ayaa laga sameeyay darbiga cirifka, markii qaybta koodhka la gaarey, dib-u-buuxinta ayaa ka dhacday korka kore ee cirifka.Markii dib-u-buuxinta ay gaartay albaabka laga soo galo, waxaa jiray isbeddel qaab dhismeedka qulqulka ah, dalool weyn oo faaruq ah ayaa dib loo habeeyey iyo habka soo noqnoqda
Qaabaynta qalalaasaha horumarsan ee jilitaanka CFD waxay soo saartay natiijooyin aad uga saxsan moodooyinka caadiga ah marka la barbar dhigo natiijooyinka tijaabada ah.
CFD-du waxa ay u dhigmatay dalool-xumada weyn ee maran ee ku teedsan cirifka iyo dhacdada dib-u-buuxinta.
Inta jeer ee habdhaqankan ee natiijooyinka CFD sidoo kale waa lagu raacay tijaabada.
CFD waxay daaha ka qaaday in heerka qulqulka qulqulku uu sidoo kale ahaa mid kacsan, oo ku xidhan habdhaqanka cavitation ee kor lagu sharaxay.Xaqiiqda ah in celceliska Cd ee CFD uu ku raacay in lagu cabbiray tijaabada ayaa siisay kalsooni ah in garaaca qulqulka CFD uu sax yahay.
Isticmaalka LSM-yadu waxay awood u siiyeen horumarinta moodooyinka LES CFD ee waqti-koob la maamuli karo.Tani waxay badbaadisay waqti badan si loo soo saaro moodooyinka qaybaha cabbirka dhabta ah.
Xaaladda duritaanka dhabta ah, inta jeer ee daloolka garaaca ayaa aad u sarreeya si uu saameyn ugu yeesho waxqabadka matoorka.Ka warqabka ifafaalaha ay bixiso shaqadani waxay awood u siin doontaa wax kasta oo waxyeello keeni kara in laga fogaado heerarka naqshadeynta mustaqbalka.
