EM3019: FLUID MECHANICS (2021-2022)

Last modified: 20 Oct 2021 09:35


Course Overview

The course begins with dimensional analysis and the concept of dynamic similarity applied to fluid flow phenomena.  This is followed by sections on the energy and momentum equations applied to a range of problems in civil, mechanical, chemical and petroleum engineering, including steady flow in pipes, design of pump-pipeline systems, cavitation, forces on bends, nozzles and solid bodies, turbomachinery and propeller theory.  A section on unsteady flow applies inertia and water hammer theory to the calculation of pressure surge in pipes.  The final section deals with flow through porous media such as flow through soils and rocks.

Course Description

  1. Similarity & Dimensional Analysis: dynamic similarity, common dimensionless numbers and scaling laws; Buckingham PI method; applicaitons (5 Lectures - Professor O'Donoghue);
  2. Energy Equation & Applications:  derivation of steady flow energy equation; applications to steady flow in pipes, systems with pumps and turbines, cavitation issues and pump-pipeline matching  (5 Lectures - Professor O'Donoghue);
  3. Unsteady Flow in Pipes: inertia head; water hammer; surge protection (5 Lectures - Profesor O'Donoghue);
  4. Momentum Equation & Applications:  derivation of momentum equation; application to forces of jets on plates, vanes, pipe bends and nozzles; propeller theory and wind turbines; radial flow reaction machines  (5 Lectures - Professor O'Donoghue);
  5. Porous Media Flow:  porous media properties; permeability and Darcy's law; confined and unconfined flows; wells  (5 Lectures - Dr Tanino). 

Each student does two extended laboratory exercises, one on hydraulic machines and another on unsteady pressure surge and water hammer.  The exercises are 'extended' as they involve analysis and consideration of results outside of the laboratory hours.
