| dc.description.abstract | Straipsnyje nagrinėjamas Vilniaus Gedimino technikos Pastatų energetikos katedros (PEK) mokomasis aerodinaminis vamzdis, su kuriuo galima atlikti laboratorinius darbus ir nesudėtingus mokslinius tyrimus. Pateikta PEK aerodinaminio vamzdžio darbinės kameros įtekėjimo ir ištekėjimo greičių projekcija, taip pat atliktas faktinis triukšmo lygio matavimas, kuris lyginamas su ventiliatoriaus gamintojų pateiktu triukšmo lygiu. Siekiant įvertinti kompiuterinės programos patikimumą, atliktas kompiuterinis modeliavimas programa PHOENICS. Modeliavimo tikslas – sumodeliuoti bandomąjį modelį, gautus rezultatus palyginti su analogiško bandymo rezultatais, pateiktais moksliniuose straipsniuose. | lit |
| dc.description.abstract | The paper analyzes an educational wind tunnel produced by the Department of Building Energetics (DBE) of Vilnius Gediminas Technical University. The equipment could be used for performing laboratory works and simple research. The article presents the projection of inflow and outlet velocity in the working chamber of DBE wind tunnel and carries out actual noise level measurement. The received data are compared with information on the level of noise generated by the fan considering instructions provided by the manufacturer. In order to assess the reliability of the computer program, simulation applying PH OENICS software has been conducted. The aim of modeling is to simulate a pilot model and to compare the obtained results with those of an analogous test presented in scientific articles. | eng |
