Course Objective:

To learn the basics and advanced concepts of fluids and fluid flow including flow of compressible fluids, laminar and turbulent boundary layer flows and multiphase flow.

 

Introduction: Basic fluid flow concepts, Velocity and stress fields, Classification of fluids, Fluid kinematics, Navier-Stokes Equation, Energy equation (Bernoulli), Pipe flows, Pumps and compressors.

 

Flow of Compressible Fluids: Basic Equations and assumptions, Isentropic flow through nozzles, Adiabatic friction flow, Isothermal friction flow, Sonic and Sub-sonic flows

 

Boundary Layer: Laminar and turbulent boundary layer flows, Boundary layer parameters, Prandtl’s boundary layer equations, Blasius solution, von-Karman momentum integral equation, Boundary layer separation.

 

Flow Pattern: Flow pattern of gas-liquid and liquid- liquid concurrent flow in horizontal and vertical tubes.

 

Pressure Drop and Hold-up:  Holdup relations for various multiphase flow regimes, Friction factor models and Correlations of Lokhart-Martinelli and Hughmark, Evaporating and condensing one component flow, Equations of change with interphase transport.

 

Drops and Bubble Dynamics: Formation of drops and bubbles, Motion of single drops and bubbles, Effect of circulations and interaction for drops and bubbles.
