Fluid Mechanics

Indian Institute of Technology Kanpur

This is intended to be a first course in fluid mechanics for undergraduate students in chemical engineering.The course will begin by introducing the necessary fundamental concepts of fluid flow, and proceed to cover both macroscopic (i.e. integral balances) and microscopic (i.e. differential balances) approaches to analyze various fluid flow phenomena encountered in chemical engineering applications. Some specific applications that will be covered in detail are:

  1. Pipe flows, fittings and friction factor charts,
  2. Fow past immersed bodies: drag forces, settling,
  3. Flow through packed beds and fluidized beds,
  4. Fluid transportation (pumps, compressors and valves),
  5. Flow measurement techniques, and
  6. Agitation and mixing.

Apart from these applications, the following specialized topics that are relevant to chemical engineers will also be covered:

  1. Boundary layer theory,
  2. Non-Newtonian and viscoelastic fluids, and
  3. Turbulent flows.

A number of problems will be worked out alongside to help illustrate the concepts.

Course contents: Introduction to process fluid mechanics; Fluid statics; Macroscopic (integral) balances for mass, energy and momentum with applications; Engineering Bernoulli equation.Microscopic (differential) balances (Navier-Stokes equations) with simple applications; Dimensional analysis; Inviscid and potential flows; Boundary layer theory.Pipe flows and friction factor charts; Flow past solid bodies; Flow through packed and fluidized Beds; Agitation and mixing; Flow measurement; Fluid transportation: pumps & compressors; Brief introduction to non-Newtonian fluids; Turbulent flows.
