| Popis: | U radu je obrađen proces nastajanja kavitacije, uzroci koji dovode do njene pojave, kao i posledice koje izaziva na materijalima. Razmotren je uticaj kavitacije na delove brodskih dizel motora koji se hlade vodom, kao i kavitacione erozije na površine cilindarskih košuljica hlađenih vodom. Težište rada posvećeno je uzrocima nastajanja kavitacije na rashladnim površinama brodskih dizel motora, a posebno uticaju vrste rashladne tečnosti, pritiska i temperature na gubitak mase modela ispitivanih na kavitaciju u jednakim uslovima i na istom uređaju. Posebno je izvršena analiza i upoređenje kavitacionih razaranja od pritiska i temperature rashladne tečnosti. / This paper -work presents the cavitation arises, causes of its appearing and consequences which it setup on materials. It represents the influence of cavitation on parts of marine Diesel engines cooled by -water, as -well as, influence of cavitation erosion on surface of the cylinder liner cooled by water. The focus of this paperwork is the influence of cavitation appearing on cooling surfaces of marine Diesel engines, and specially the influence of cooling fluid type, pressure and temperature on the loss of mass of models examined on cavitation in equal conditions and on the same device. Particularly performed analysis and comparison of cavitation destruction dependent on pressure and temperature of cooling fluid. |
