BM1009 BIO-FLUID AND DYNAMICS 3 0 0 100
To study the properties and types of flow. The pressure developed and the flow pattern for different types of flows and tubes. This will help to analyse the fluid dynamics in cardiac vessel and across the valves.
• To classify the fluids according to its characteristics.
• To study the pressure and flow patterns in blood vessels.
• To use this knowledge in studying the mechanics available at
1. INTRODUCTORY CONCEPTS 9
Fluids and non-fluids, continuum coordinate systems, force and moments, stress at a point, rate of strain, properties of fluids, classification of fluids.
2. FLUID FLOW 9
Different types of fluid flows, laminar and turbulent flow, transition from laminar to turbulent flow, laminar flow-annulus, laminar flow between parallel plates, measurement of viscosity.
3. BOUNDARY LAYER FLOW 9
Development of boundary layer, estimates of boundary layer thickness, boundary layer equation, nature of turbulence, smooth and rough surface, boundary layer separation.
4. PRESSURE AND FLOW IN BLOOD VESSELS 9
Friction loss in flow in a tube, velocity distribution of aortic system, waveform of pressure and velocity in aorta, wave reflections and impedance in arterial segments, blood flow in veins and blood flow in capillaries.
5. ANALYSIS OF CARDIO VASCULAR DYNAMICS 9
Control theory and system analysis, mechanical analysis of circulatory systems, basic concept of myocardial mechanics, index of contractibility, fluid dynamics of aortic and mitral valves.
