An Investıgation of the Left Ventrıcle of Human Heart by Fluıd-Dynamıcs Modelıng
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 5
Abstract
In this study an echocardiography device in Azadi Scientific Hospital of Duhok, Kurdistan - Iraq has been used to mesure the Left Ventricle (LV) wall thickness of three Patient groups: control (19 patients), smoking (15 patients) and asthma (9 patients) using a simulation method based on Computational Fluid Dynamics (CFD). The study is based on the design of a computational model of the human Left Ventricle using specific data (IVSd, LVIDd, LVPWd, IVSs, LVIDs and LVPWs) taken from the 2D M-mode echocardiography of selected groups. However, the phase diastole data are used to simulate blood flow inside LV by ANSYS FLUENT V14 based on CFD technology and the information have been used to build a numerical mesh for CFD simulation which provides detail 2D LV velocity and pressure distributions in the LV cavity. Finally, the data for the three groups are analyzed by SPSS V1 to observe how the diseases can affect on the LV two phases (systole and diastole) parameters. The effects of the diseases (asthma, smoking and control), of the Age , of the Sex and of the Body Mass Index (BMI) have been observed.
