Daloosha firfircoon ee gudaha duritaanka naaftada waxqabadka sare leh - tijaabo tijaabo ah iyo CFD(qaybta 2)
Jilitaanka CFD, xallinta qaab-dhismeedyo qallafsan oo baaxad leh iyadoo la adeegsanayo moodooyinka ku saleysan Eddy Simulation (LES) waxay muujinayaan faa'iidada qaabaynta ku meel gaadhka ah ee jilitaanka RANS [3] [4] [5]. Khasaaraha halista ah ee LES ku salaysan CFD ee jawiga warshadaha ayaa ah kheyraadka xisaabinta ee weyn ee loo baahan yahay, ee isku xigxiga dhowr boqol oo kombuyuutar ah. La'aanteed kheyraadkan oo kale, waqtiga loo ordayo hal kiis wuxuu qaadan karaa bilo, taasoo ka dhigaysa baaritaanno halis ah mid aan suurtagal ahayn waqti macquul ah.
Horumarro la taaban karo ayaa lagu sameeyay qaabaynta CFD taasoo isku dayaysa in la isku daro faa'iidooyinka qaabaynta qalalaasaha ee LES iyo RANS labadaba. Moodooyinkan waxaa badanaa loogu yeeraa moodooyinka isku-dhafan waxayna siinayaan awood weyn oo LES ah in laga isticmaalo gudaha jawi warshadeed.
Qaab isku-dhafan oo LES-RANS CFD ah, iyadoo la adeegsanayo hab isku dhaf ah oo wajiyo badan leh oo loogu talagalay cavitation ayaa la sameeyay si loo ekaysiiyo waxqabadka marinka gacanta. Qaabaynta qallafsanaanta iyadoo la adeegsanayo habka isku-dhafan ee LES-RANS wuxuu u oggolaanayaa guulo xisaabineed oo la taaban karo oo ka sarreeya LES buuxa, gaar ahaan lambarka Reynolds-ka sare (Re) joomatari socodka qulqulka derbiga ee ku dhex jira duriyaha naaftada.
2. Shaqo tijaabo ah
Noocyo hufan ayaa laga sameeyay qaybo ka mid ah kantaroolka hawo-biyoodka oo laga soo dhex muday mudiye naafto ah, oo ay ku jiraan dusha sare ee kantaroolka cadaadiska, inta u dhaxaysa cirbadda sare iyo waalka kantaroolka. Sababtoo ah miisaanka yar ee cirbadaha dhabta ah ee dhabta ah qaabka waxaa la abuuray 40 jeer dhabta ah, sida lagu muujiyay daraasadihii hore in waxqabadka socodka qulqulka uu si macquul ah uga madaxbannaan yahay miisaanka [1]. Miisaankan la kordhiyey wuxuu oggolaaday fududayn weyn oo muuqaal ah iyadoo la adeegsanayo kamarad xawaare sare leh, a Vision Research Phantom V1210. Kamarada noocan oo kale ah oo leh nal ku habboon ayaa soo qaadata faahfaahinta socodka aan la arki karin indhaha bini'aadamka, waxayna u ogolaataa habdhaqanka hydraulic in lagu raad raaco habka cavitation.
