Rationale and Purpose of the Module:

To advance the knowledge of the students of fluid flow, aerodynamics and convective heat transfer

Syllabus:

The Derivation of the Three-Dimensional Viscous, Steady, Compressible Equations of the Conservation of Mass, Momentum and Energy. The Distinction between Differential and Integral Solutions. Differential Solutions for Simple Pipe Flow with Heat Transfer and Couette Flow. The Von-Karmen Integral Solution of Flat Plate Flow with Heat Transfer. Dimensional Analysis for Free and Forced Convection: the Non-dimensionalised Differential Equations. Shear Stress Drag and the Reynolds Colburn Analogy. Theories of Turbulence: The Prandtl - Mixing Layer Theory, the K-E Model. The Effect of Turbulence on Drag and Heat Transfer: The Elements of a Turbulent Boundary Layer

Learning Outcomes:
