Syllabus

Basic Concepts and Fundamentals, definition and properties of Fluids, Governing Equations of Fluid Motion, Continuum approximation Cylindrical and spherical coordinates, fundamental theorems of calculus: Stokes theorem Lagrangian and Eulerian viewpoint, Fluid kinematics: Decomposition of Motion General conservation equation, Conservation of mass, Conservation of linear and angular momentum, Reynolds transport theory Pressure, Stress tensor, rate of deformation tensor, Navier-Stokes equation, Boundary conditions Dimensional analysis, Approximate forms of Navier-Stokes equation, Stokes equation, Euler’s eqution, Exact solutions of Navier-Stokes Equations: Couette flows, Poiseuille flows, Fully developed flows in non circular cross-sections, Unsteady flows, Creeping flows Unidirectional and nearly unidirectional flows, Lubrication flows Boundary layer theory Introduction to non-Newtonian fluids, Generalized Newtonian fluids, viscoelastic fluids.

Course Objectives

  1. The student will understand stress-strain relationship in fluids, classify their behavior and also establish force balance in static systems. Further they would develop dimensionless groups that help in scale-up and scale-down of fluid flow systems.
  2. Students will be able to apply Bernouli principle and compute pressure drop in flow systems of different configurations
  3. Students will compute power requirement in fixed bed system and determine minimum fluidization velocity in fluidized bed
  4. Students will be able to describe function of flow metering devices and apply Bernoulli equation to determine the performance of flow-metering devices

Course Outcomes

The course is intended to provide students with the following benefits:
1. Ability to derive governing equations for momentum transport
2. Understanding the physical meaning of general equations in fluid flow phenomena
3. Ability to address problems in Chemical engineering, and to solve the problems.
