Objectives and Outcomes

Course Objectives

  • To familiarize kinematic and dynamic behaviour of fluid flow
  • To introduce Navier-Stokes equationpertinent to steady and unsteady flows
  • To introduce flow dynamics over immersed bodies
  • To impart knowledge on origin and nature of turbulence

Course Outcomes

  • CO1: Evaluate instantaneous fluid velocity and track the fluid particles in the flow field, compute flow rate and pumping power of the fluid
  • CO2: Solve benchmark problems using NSE to estimate the velocity profile and shear stress
  • CO3: Apply NSE in real time engineering problems to model low and high Reynolds number flow and boundary layer flows
  • CO4: Estimate the total drag and lift forces associated with structures immersed in the fluid
  • CO5: Predict the length scale of eddies and Reynolds stress
