SIMULACIJA STRUJANJA FLUIDA KORIŠTENJEM OPENFOAM-A SLUČAJ 29 - STRUJANJE KROZ REŠETKU S PROFILIMA OBLIKA 3

Tema ovoga rada bila je simulacija strujanja fluida korištenjem OpenFOAM-a, pri čemu je bilo potrebno CAD geometriju profila rešetke diskretizirati mrežom konačnih volumena te izračunati i prikazati turbulentni tok za četiri odabrane brzine. Zadan je bio oblik profila rešetke za koga je trebalo izračunati pad tlaka zbog gubitaka koje njegovo optjecanje uzrokuje. Također je bilo potrebno izračunati pripadajuće vrijednosti empirijskim formulama te na kraju usporediti dobivene rezultate.The main purpose of this thesis is the flow simulation obtained with the program OpenFOAM. The first step is to import the CAD geometry and to do the discretisation with the final volume mesh, and after that to calculate and show the results that describe the turbulent flow for four chosen velocities. The main problem is determining the local losses that occur in a flow through a grid with bars of defined geometry. Those losses are also calculated with empirical formulas and the results are in the end compared with the results obtained with the simulation
