Iziphumo zomoya zibaluleke kakhulu ekukhetheni okulungileyoumthamo woluvo lweselikunye nokumisela ufakelo oluchanekileyo lokusetyenziswa kwiizicelo zangaphandle.Kuhlalutyo, kufuneka kucingelwe ukuba umoya unako (kwaye wenza) ukuvuthuza nakweliphi na icala elithe tye.
Lo mzobo ubonisa ifuthe lomoya kwitanki eme nkqo.Qaphela ukuba akukhona kuphela ukusabalalisa uxinzelelo kwicala lomoya, kodwa kukho ukusabalalisa "ukufunxa" kwicala leeward.
Imikhosi emacaleni omabini etanki ilingana ngobukhulu kodwa ichasene kwicala kwaye ngoko ayinayo impembelelo ekuzinzeni okupheleleyo kwenqanawa.
Isantya somoya
Esona santya siphezulu somoya sixhomekeke kwindawo yejografi, ukuphakama kunye neemeko zendawo (izakhiwo, iindawo ezivulekileyo, ulwandle, njl. njl.).IZiko leSizwe leMeteorological Institute linokubonelela ngeenkcukacha-manani ezongezelelekileyo ukumisela ukuba isantya somoya kufuneka siqwalaselwe njani na.
Bala amandla omoya
Ufakelo luchaphazeleka kakhulu ngamandla anqamlezileyo, asebenza kwicala lomoya.La mandla angabalwa ngoku:
F = 0.63 * cd * A * v2
Ilapha:
cd = i-coefficient yokutsala, kwi-cylinder ethe tye, i-coefficient yokutsala ilingana no-0.8
A = icandelo eliveziweyo, elilingana nobude besikhongozeli * isikhongozeli sedayamitha yangaphakathi (m2)
h = ubude besikhongozeli (m)
d = umngxuma wenqanawa (m)
v = isantya somoya (m/s)
F = Amandla omoya (N)
Ke ngoko, kwisikhongozeli esithe nkqo, le fomula ilandelayo ingasetyenziswa:
F = 0.5 * A * v2 = 0.5 * h * d * v2
Ukuququmbela
•Ufakelo kufuneka luthintele ukubhukuqa.
• Izinto zomoya kufuneka ziqwalaselwe xa ukhetha umthamo we-dynamometer.
•Njengoko umoya ungasoloko uvuthuza kwicala elithe tye, indawo ethe nkqo inokubangela iimpazamo zomlinganiselo ngenxa yokutshintsha kwenqaku elinguziro.Iimpazamo ezinkulu kune-1% yobunzima bobunzima bunokwenzeka kuphela kwimimoya enamandla kakhulu> 7 Beaufort.
Iziphumo kuLayisha iSeli yokuSebenza kunye noFakelo
Impembelelo yomoya kwizinto zokulinganisa amandla zahlukile kwimpembelelo kwiinqanawa.Amandla omoya abangela umzuzu wokubhukuqa, oya kulungiswa ngumzuzu wokusabela kwiseli yomthwalo.
Fl = amandla kwinzwa yoxinzelelo
Fw = amandla ngenxa yomoya
a = umgama phakathi kweeseli zomthwalo
F*b = Fw*a
Fw = (F * b)∕a
