I-Fluid mechanics yinxalenye yobuchwephesha kunye nobuchwephesha bemidiya eqhubekayo eziziinkalo eziphambili kwi uqeqesho lobunjineli. Ikhosi esiyinikelayo yintshayelelo kumatshini wolwelo, ifundiswa njengenxalenye yoqeqesho jikelele lwabafundi bobunjineli, inokuba luncedo kakhulu kubafundi baseyunivesithi okanye abazifundisayo.
Ngokumalunga neziseko zoomatshini bolwelo, siya kugxininisa kakhulu kumgaqo-siseko we iiequations ezingundoqo zokuhamba ngokucacileyo kusetyenziswa imigaqo yobuxhakaxhaka kunye nefiziksi encediswa luqikelelo lwemvelaphi yomzimba kubume bamanzi kunye nokuhamba.
Siza kugxininisa intsingiselo ebonakalayo yeequations kwaye siza kubona indlela yokuzisebenzisa kwiimeko eziphathekayo. I izicelo ubuchwephesha be-fluid baninzi kwiimoto, kwi-aeronautics, ubunjineli boluntu, ubunjineli bemichiza, i-hydraulics, isicwangciso sokusetyenziswa komhlaba, amayeza, njl.
Kule ndlela yokuqala kubuxhakaxhaka be-fluid siyakumisela umda kwikhosi ulwelo olungacinezelekiyo ukuhamba ngokusisigxina okanye hayi. Ulwelo luya kuthathwa njengosasazo oluqhubekayo. Siza kufowuna isuntswana, into enomthamo omncinci ngokungenasiphelo kwinkcazo yezibalo kodwa inkulu ngokwaneleyo ngokumalunga neeathomu eziza kuchazwa ngemisebenzi eqhubekayo.
