Abstract

Hidrodinamički tunel i kanal su uređaji za merenje hidrodinamičkih veličina plovnih objekata na vodi i u vodi, kao i profila i profilnih rešetki turbomašina. Hidrodinamički tunel je sa zatvorenim tokom strujanja i četvorostranim kružnim tokom. Pokretanje vode se vrši vodnim mlaznim motorom (4) a protok se meri blendom (7). Model (9) koji se ispituje smešta se u tunel (8), a vezuje se za tunel osovinama (12). U zavisnosti od toga šta se želi meriti očitavanja se vrše na odgovarajućim instrumentima kao što je sila otpora (19) kretanja i uzgonska (13) sila. Hidrodinamički kanal je varijanta hidrodinamičkog tunela a razlika je u tome što je tunel (8) zamenjen kanalom (8a).[Hydrodynamic tunnel and canal are devices for measuring hydrodynamic size of vessel objects on water and in water, just like profiles and profiled bars of turbomachines. Hydrodynamic tunnel has closed stream current and four side circular curvent. The movement of water is performed by water jet engine (4) and the current is measured by a blend (7). Model (9) that is being investigated is placed in a tunnel (8), and connected to the tunnel with axes (12). Depending on what we wish to measure, the readings are performed on appropriate instruments, such as power of resistance (19) to movement and drive (13) power. Hydrodynamic canal is variation of hydrodynamic tunnel and the difference is in the fact that the tunnel (8) has been replaced with canal (8a).
