Introduction: Basic fluid flow concepts, Velocity and stress fields, Classification of fluids, Fluid kinematics, NavierStokes 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 Subsonic flows
Boundary Layer: Laminar and turbulent boundary layer flows, Boundary layer parameters, Prandtl’s boundary layer equations, Blasius solution, vonKarman momentum integral equation, Boundary layer separation.
Flow Pattern: Flow pattern of gasliquid and liquid liquid concurrent flow in horizontal and vertical tubes.
Pressure Drop and Holdup: Holdup relations for various multiphase flow regimes, Friction factor models and Correlations of LokhartMartinelli 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.
