Poboljsanje toplotnih performansi razmenjivača toplote u6radnj0m turbulizatora
Apstrakt
U raduje analiziran uticaj ugradnje turbulizatora u cevne elemente na poboljšanje toplotnih performansi razmenjivača toplote. Prikazani su turbulizator koji se najčešče koristi za cevaste razmenjivače toplote kao i uporedna analiza efekta koji se postiže ugradnjom turbulizatora. Izloženi su rezultati sopstvenih eksperimentalnih istraživanja u cilju određivanja koeficijenta prolaza toplote razmenjivača toplote sa ugrađenim turbulizatorom u obliku zavojne žice.
