Iziphumo zomoya zibaluleke kakhulu ekukhetheni ichanekileUmthwalo we-selsor yeselikunye nokwenza ufakelo oluchanekileyo lokusebenzisa ngaphakathiIzicelo zangaphandle. Kuhlalutyo, kufuneka icinge ukuba umoya ungathi (kwaye) kuvuthuza kulo naliphi na icala elithe tyaba.
Lo mzobo ubonakalisa isiphumo somoya kwitanki elithe nkqo. Qaphela ukuba kungekuphela nje kukho ukuhanjiswa koxinzelelo kwicala lomoya, kodwa kukho ne "cwaka" ngokusasazwa kwecala lebase.
Imikhosi kumacala omabini etanki ilingana nobukhulu kodwa ngokuchaseneyo kwaye ngenxa yoko ayinasiphumo kuzinzo senqanawa.
Isantya somoya
Isantya esiphezulu somoya sixhomekeke kwindawo yendawo, ubude kunye neemeko zasekhaya (izakhiwo, iindawo ezivulekileyo, ulwandle, njl njl.). IZiko leMeko yeSizwe linokubonelela ngamanani amaninzi okumisela indlela ezenza ngayo isantya somoya.
Bala amandla omoya
Ukufakwa kuchaphazeleka ikakhulu yimikhosi ethe tyaba, yenza kwicala lomoya. La mandla anokubalwa ngu:
F = 0.63 * CD * A * v2
Ilapha:
I-CD = Tsala i-couded, isilinda esithe nkqo, i-coanded ilingana no-0.8
A = icandelo elibonisiweyo, elilinganayo lokuphakama kwekhontelo * ye-Inner engaphakathi (M2)
h = ukuphakama kwe-interner (m)
d = umngxunya wenqanawa (m)
v = isantya somoya (m / s)
F = amandla oveliswe ngumoya (n)
Ke ngoko, kwisikhongozeli esithe tye, kusetyenziswe le fomula ilandelayo:
F = 0.5 * A * v2 = 0.5 * h * d * v * v * v2
Ukuququmbela
• Ufakelo kufuneka lithintela ukuqasha.
Izinto zomoya kufuneka ziqwalaselwe xa ukhetha umthamo we-Dynamemeter.
Ukusukela kuba umoya awusoloko uvuthuza kwicala elithe tyaba, icandelo elithe nkqo linokubangela iimpazamo zemilinganiselo ngenxa yokutshintsha kwe-zero. Iimpazamo ezinkulu ezikhulu kune-1% yobunzima bomnatha zinokwenzeka kuphela kwimimoya enamandla kakhulu> 7 i-7 yeBeape.
Iziphumo ekusebenzeni kweselfowuni kunye nokufakwa
Isiphumo somoya ekunyanzelweni okunyanzeliswa kwemigangatho yokulinganisa yahlukile kwifuthe kwiinqanawa. Amandla omoya ebangela umzuzu wokubhukuqa, oya kuthi aphelelwe ngumzuzu wokuphendula kwiseli yomthwalo.
Fl = nyanzela inzwa yoxinzelelo
Fw = amandla ngenxa yomoya
A = umgama phakathi kweeseli zomthwalo
F * b = fw * a
Fw = (f * b) / a
