Umbhobho wombhobho ubizwa nangokuthi isikhulisi somoya. Isebenzisa isimiso sikaBernoulli ukukhiqiza indawo engenela isikhala ekugcineni kombhobho, engamunca zonke izinto ezizungezile embhobho bese uyixuba nomoya ocindezelweyo. Izinga lokugeleza kwejet lalo likhulu kunokugeleza kwegesi okucindezelwe kungene ngomlomo. Izikhathi ezi-5 kuye kweziyi-15, kusetshenziswa lesi sici, umbhobho uvame ukusetshenziselwa ukushaya okomisa, ukuhambisa into, ukuhlanza uthuli, njll.

Kusukela emiphumeleni yokubala yesoftware yeCFD, siyabona ukuthi igesi ecindezelweyo engena embhobho kusuka ngezansi icindezelwa ngaphakathi kombhobho futhi ikhishwe ngakwesokudla ngejubane eliphakeme kakhulu, ngaleyo ndlela kwakheke indawo engenalutho ngakwesobunxele. Ukudonswa lapha kukhulu ngokwedlulele. Njengokungeniswa kwempahla, okokusebenza kuthunyelwa ngokuzenzakalela kwezinye izindawo, noma kungavulwa njengesengezo segesi ecindezelweyo, kusetshenziswa umbhobho wombhobho ukusula ubuso bento, noma ukukhipha imfucumfucu.

Uma ufuna ukuthola imininingwane ethe xaxa yezobuchwepheshe mayelana nemibhobho yomshini, noma uthole ikhotheshini yomkhiqizo ephansi, sicela ukhululeke ukuxhumana nathi.
