A three-dimensional and pulsatile blood flow in the left ventricle of heart model has been studied numerically. The geometry was derived from a simple approximation of the left ventricle model and the numerical simulations were obtained using a formulation of the Navier-Stokes equations. In this study, simulation was used to investigate the pattern of flow velocity in 3D model of heart with consider the left ventricle based on critical parameter of blood under steady condition. Our results demonstrate that flow velocity focused from mitral valve channel and continuous linearly to left ventricle wall but this skewness progresses into outside wall in atrium through aortic valve with random distribution that is irregular due to force subtract from ventricle wall during cardiac cycle. The findings are the prediction of the behavior of the blood flow velocity pattern in steady flow condition which can assist the medical practitioners in their decision on the patients- treatments.<\/p>\r\n","references":"[1] Hang Gao, Florence Kremer, Hon Fai Choi, Jens-Uwe Voigt, Piet Claus\r\nand Jan D-hooge, \"Left ventricular 2D flow pattern estimation of the\r\nheart by combining speckle tracking with Navier-Stokes based\r\nregularization\", pp. 1068-1071, ISBN: 978-1-4577-0382-9, 2010\r\n[2] Bernardo Baccani, Federico Domenichini, Gianni Pedrizzetti, \"Model\r\nand influence of mitral valve opening during the left ventricular filling\",\r\nJournal of Biomechanics, vol. 36, 2002, pp. 355-361.\r\n[3] M.A.H.
