Abstract:
S pomočjo računalniškega programa na osnovi računalniške dinamike tekočin smo parametrično analizirali pretok skozi aortno zaklopko. Osredotočili smo se na primerjavo aortnih zaklopk z različnimi stopnjami pojavnosti insuficience. Želeli smo prikazati odvisnost med stopnjo obolelosti aortne zaklopke z insuficienco in posledicami v delovanju človekovega organizma. Numerični model je upošteval kri kot nenewtonsko tekočino s potenčnim zakonom ter predpostavljal neelastično geometrijo. Rezultati kažejo, da je delovanje aortne zaklopke v organizmu zelo pomembno, insuficienca pa bistveno spremeni tokovne razmere pri delovanju srca.

Title:
Parametric analysis of flow through aortic valve
Abstract:
Using the Computational Fluid Dynamics, we parametrically analysed flow through aortic valve. We focused on comparison of aortic valves with different levels of regurgitation. We wanted to show dependence between the level of aortic valve disease and consequences in human organism functioning. Numerical model considered blood as Non-Newtonian fluid with a Power Law and assumed inelastic geometry. Results show that aortic valve operating in organism is very important and regurgitation significantly changes flow conditions at heart functioning.
