Abstract
Cilj zadatka „Analiza pulsirajućeg strujanja viskoznog fluida u krvnim žilama“ je usporediti analitički i numerički model te pokazati da se dobivaju jednoznačna rješenja. Numerički model može se prikazati kao varijanta s konstantnim koeficijentom trenja te kao Cassonov model trenja. Koristeći modificirane jednadžbe Navier-Stokesovog strujanja, zadano je strujanje prikazano je kao nestlačivo s harmonijskim gradijentom tlaka u cilindričnom koordinatnom sustavu. Radi lakšeg uspoređivanja numeričkog i analitičkog modela jednadžbe su u bezdimenzijskom obliku. Kao promjenjive ulazne veličine korišten je samo bezdimenzijski Womerslyjev broj te OMJER kod Cassonovog modela. Brzina, smično naprezanje i protok u funkciji prostorne i vremenske koordinate računate su kao izlazne varijable.
Abstract (english)
The aim of assignment "Analysis of Pulsatile Flow in Blood Vessels" is to compare analytical and numerical model and to show that both result are identical. Numerical model can be shown as a variant with a constant coefficient of friction and also as Casson model of friction. Using mofdified equations of Navier-Stokes flow, given flow is presented as incompressible with harmonic gradient of pressure in cylindrical coordinate system. Due to easier comparation of numerical and analytical model, the equations are in dimensionless form. As variable inputs are used only dimensionless Womersly number and RATIO with Cassan model. Speed, shear stress and flow in function of spatial and temporal coordinate are beeing calculated as variable outputs.
