1. THE EXACT SPECIFICATION FOR CONSUMPTION OF BLOOD-PRESSURE REGULATING DRUGS WITH A NUMERICAL MODEL OF PULSATILE MICROPOLAR FLUID FLOW IN ELASTIC VESSEL

Authors: H. ASKARIAN , S. GHOLAMREZAIE, , S. MADDAH

Abstract: In the present paper, the problem of pulsatile micropolar blood flow through an elastic artery has been studied. An Arbitrary Lagrangian-Eulerian (ALE) formulation of the dominate equations have been produced to model the fully-coupled Fluid-Structure Interaction (FSI). Furthermore, those derived equations have also been numerically dealt with using finite difference scheme through exploiting a mesh generation technique which leads to a uniformly spaced grid in the computational plane. The effect of variations in cardiac output and elastic modulus of artery wall on blood pressure has been determined by utilizing blood-pressure regulating drugs like Atenolol. Also a numerical model has been prepared in order to precisely define and verify the effects of various dosage of a drug on blood flow in arteries without resorting to the inefficient prevalent experiments that could have many mistakes and costs. The numerical results have shown that the artery wall stiffness has been decreased abo

2. CHARACTERIZATION METHOD OF ENGINE AIR BEHAVIOUR FROM A REAL HEAD-CYLINDER

Abstract: This study is based on a head-cylinder provided by a French car manufacturer, which comes from a 4-cylinder 4-stroke spark-ignition engine. This head-cylinder adopts a Double-Over-Head-Camshaft (DOHC) with 16 valves, also two per cylinder. The purpose of this paper is to propose a characterization method of the air behaviour inside both the intake conduct of a head-cylinder and the cylinder. The cylinder stroke is known (from the cylinder capacity of the engine) as well as the valve dimensions (by measurements) but none internal dimensions of the conduct. The proposal method follows three main steps: firstly, internal features are extracted separately by moulding with a silicon-calcium mixture, to realize the geometrical limits of the air. This step concerns only the conduct and the combustion chamber of the head-cylinder. Secondly, the two features and one of the two valves are digitized with a Faro® laser arm to compose cloud points of their shapes. Surfaces can be then reconstituted
