Abstract
Laminarni tok je tip strujanja tekućine u kojem nema međusobnog miješanja slojeva. Tekućina se nalazi u laminarnom načinu strujanja sve dok se ne dosegne kritična vrijednost Reynolds-ovog broja. Nakon toga smatramo da je strujanje tekućine postalo turbulentno. To tečenje karakterizira konstantno međusobno miješanje slojeva tekućine. Kritična vrijednost Reynolds-ovog broja bit će različita ovisno o tome odvija li se strujanje unutar zatvorenih cijevi, otvorenih kanala ili kod podzemnih voda. Vrijednost tog parametra ovisi o brzini strujanja tekućine, kinematskom koeficijent viskoznosti te odabranoj duljini. U slučaju laminarnog strujanja preko neke krute plohe pojavljuje se određeni granični sloj između središta toka i krute plohe. Taj sloj započinje kao laminarni tok ali s porastom puta polako prelazi u turbulentni način strujanja.
Abstract (english)
Laminar flow is a type of fluid flow in which there is no intermingling of the layers. The fluid is in laminar flow mode until the critical value of the Reynolds number is reached. After that, we consider that the fluid flow became turbulent. This flow is characterized by constant mixing of the fluid layers with each other. The critical value of the Reynolds number will be calculated depending on whether the flow takes place inside closed pipes, open channels or in groundwater. The value of this parameter depends on the flow rate of the liquid, the kinematic viscosity coefficient and the selected length. In the case of laminar flow over a rigid surface, a certain boundary layer appears between the flow center and the rigid surface. This layer begins as a laminar flow but with the increase of the path slowly passes into a turbulent flow mode.
