Abstract(in English) | The coronary arterial system that perforates the ventricular muscle vertically shows a helical pattern.Thus,we have analyzed the axial blood flow velocity in the steady flow in the helical tube to speculate the blood flow nature within the intra myocardial coronary artery.The cylindrical coordinates system have been converted into toroidal coordinates system by which Navier- Stokes equations have been represented.The first order perturbation solution showed the maximum value at the middle of the cross section of helical tube and forward flow at π, 4θ2π/ 4 and 6π/4θ2π,the second order solution was positive at π/4θ 3π/4π and the third solution 0θπ.These patterns were independent from radius and number of helix.Present analysis is useful for analyzing the spatial distribution of axial blood flow of intra ventricular muscle coronary arterial system. |
