By finding the value of Re, you can get approximatily your most adequate model for your problem. Read about how the Re value determines your solver in large arteries.
Ikram Cherkaoui it depends on which model artery you are using ,bcoz in each arteries the flow of blood quantinty is different so let me know which artery you are chosen.
Dear Ikram Cherkaoui do you have all profiles ploted in single graph? I have no time to check them all, but if will plot them I will suggest you which one is most commonly found in the lietrature.
In my opinion, although not perfectly, the I profile curve corresponds to the velocity profile in the iliac artery. It is certainly the best representation of those you have presented. Remember in addition the period of the function, which is most often taken in the literature as 0.8 s, which corresponds to 72 heartbeats per minute or 1 s - 60 beats per minute.
Ikram Cherkaoui Profile 2 at inlet and profile 3 at bifurcations of illiac artery , normally i dont prefer to consider profile 1 of all the plots, because profile 1 , it has some jurk in flow.
