Fluid Dynamics

Semester 1 and 2


This course focuses on basic principles in fluid dynamics. Basic mathematical concepts are reviewed and used to analyze the kinematics and dynamics of fluid motions (e.g. . solving problems related to pipe flow, energy delivery by propellers, energy extraction by turbines, modeling of blood flow in circulatory systems , and atmospheric flows).



Introduction to Mathematical Concepts in Fluid Dynamics:

  • Vector analysis and basic mathematical tools;
  • physical characteristics of the fluid state and description of flow types;
  • viscosity coefficients as they relate to laminar and turbulent flows;
  • the Poiseuille equation

Kinematics and Dynamics of Fluid Motion:

  • In-compressible and compressible fluids;
  • Euler’s equations of motion;
  • Bernoulli’s equation and its application;
  • continuity equation;
  • analyses of steady fluid flow, propeller, wind turbine, and wind velocity profile;
  • Navier-Stokes equation and descriptions of boundary layer and turbulence;
  • vertical transport of kinetic energy, mass, heat, moisture and pollutants.

Introduction to Atmospheric flows:

  • Apparent forces (Coriolis and centrifugal) in rotating coordinate systems and their effects;
  • geostrophic flows;
  • qualitative introduction to Ekman layer;
  • basic treatment of Rossby waves and Kelvin waves

The course assessment will be conducted as follows:


Two 1-hour in-course tests (equal weighting)      40%

            Final Examination

One 2- hour final written examination                60%

Students will be expected to satisfy the examiners in both components.

Learning Objectives: 


At the end of the course, students should be able to:

  • use vector analysis to derive surface and volume integrals, and apply them to solve problems in basic fluid mechanics
  • apply the Poiseuille equation to analyze the blood flow mechanism in the human circulatory system
  • describe the basic principles governing the operation of propellers, wind turbines, hydro- power systems, and determine their energy efficiencies
  • describe the concept of the ‘boundary layer’ and its application to turbulence and transport processes
  • solve problems of  turbulent motion in various liquid and gaseous
  • analyse atmospheric flows using the mathematical tools applicable to rotating coordinate systems
