Hydrodynamics (Theory)

The students will be able to –

 

CO52: Understand the basic principles of ideal fluid, such as Lagrangian and Eulerian approach, conservation of mass etc.

CO53: Use  Euler  and  Bernoulli's  equations  and  the  conservation  of  mass  to  determine velocity and acceleration for incompressible and non-viscous fluid.

CO54: Understand the concept of rotational and irrotational flow, stream functions, velocity potential, complex potential due to sink, source and doublets.

CO55: Understand the motion of a fluid element, Vorticity, Body forces, Surface forces, Stress & Strain analysis, Flow and circulation, Connectivity, Irrotational motion in multiple connected space,

CO56: Distinguish the concept of Irrotational motion of a cylinder in two dimensions, Motion of a circular cylinder in a uniform stream and two co-axial cylinders, Streaming and circulation for a fixed circular cylinder.
