Oro srauto greičio tyrimas aerodinaminio vamzdžio skerspjūvyje / Air flow velocity testing in wind tunnel cross area section

Plėta, Vidmantas 23 July 2012 (has links)
Baigiamajame magistro darbe aptariama oro srauto greičio netolygumo aerodinaminiame vamzdyje problema ir aktualumas. Išanalizuota būdinga mokslinė literatūra ir aprašyti būdingiausi oro srauto greičio darbinės dalies skerspjūvyje nustatymo metodai. Naudojant CAD aplinkos programą sumodeliuotas trimatis aerodinaminio vamzdžio modelis ir pritaikius analizės baigtiniais elementais metodą, atliktas oro srauto greičio pasiskirstymo aerodinaminio vamzdžio darbinėje dalyje ir jos viduriniame skespjūvyje tyrimas. Tyrimo rezultatai išanalizuoti ir pateiktos išvados ir siūlymai. / In this master's thesis deals discusses the inadequacy of air flow speed in wind tunnel and the relevance of the problem. Performed analysis of the scientific literature and describe the most typical technique of air flow mesurements in wind tunnel. Using a CAD program modeled three-dimensional wind tunnel model and performed air flow velocity testing in wind tunenel test section and their midle cros area section usig CFD program. The results is evaluated and stated the conclusions and suggestions.
