SummaryThis course builds on previous treatment of fluid mechanics in SCEE08003 Fluid Mechanics 2 and CHEE09013 Heat, Mass and Momentum Transfer 3. It presents fundamental concepts in fluid mechanics as a basis for chemical engineering design. Simplifications which allow analytical solutions to the 3D Navier Stokes and continuity equations are explored, including low Reynolds number flows and inviscid, irrotational flow. The use of inviscid flow coupled with boundary layer theory to model high Re flows is presented, together with current ideas on the nature of turbulence, including turbulence spectra and decay of turbulence. Turbulence models are used to predict dispersion in mixed flows and free jets. Models for predicting pressure drops in two-phase, liquid-gas flows are discussed.

Learning Outcomes
On successful completion of the course, students should be able:
a) to demonstrate an understanding of the relevance of each of the terms in the Navier Stokes Equations and to simplify the equations on the basis of a given flow geometry and Reynolds number. By choosing appropriate boundary conditions, they should be able to solve such simplified equations or set up the equations for solution.
b)to define and make use of the Velocity Potential (phi) and Stream Function (psi) for the solution of Euler's Equation of inviscid flow. They should be able to decide whether phi or psi will exist for a given flow.
c) to describe some of the effects of turbulence, to discuss theories put forward to render turbulence amenable to analysis and to use dimensional analysis along with physical constraints to analyse and predict the decay of turbulence energy. They should appreciate that turbulent motion has associated with it a spectrum of energies and frequencies. They should be able to estimate Prandtl's mixing length, based on the mean velocity profile and measurements of turbulence intensity and to determine the Kolmogorrof length and velocity scales. They should be able to comment on the relevance of these scales of turbulence in relation to fluid mixing operations, such as that occurring in stirred tanks or free turbulent jets.
d) to describe the range of flow regimes encountered in gas-liquid flows and should understand the basis of homogeneous and separated flow models for predicting pressure drops in gas-liquid flows.
