## Unit Description and General Aims

This unit will serve as an advanced course in Fluid Dynamics. The topics covered in this unit include an introduction to basic fluid equations such as Bernoulli’s Equation and an introduction to partial differential equations in fluid dynamics i.e. Navier-Stokes Equations. Students will be introduced to the continuity equation, momentum equation, energy equation and formulations of problems and identifying boundary conditions, all considered at a master level. The unit will focus on computational fluid dynamics (CFD) stressing its advantages and applications in solving real-world problems. Students will be given an opportunity to work and formulate the models necessary to study, analyse, and design fluid systems through the application of these concepts, and to develop the problem-solving skills essential to good engineering practice of fluid dynamics in practical real-world applications.

## Learning Outcomes

On successful completion of this Unit, students are expected to be able to:

- Derive governing equations for fluid flow using best practice and use them as guidelines to make judgements on fluid mechanic problems.

* Bloom’s Level 5*

* 2. *Develop a strong physical and conceptual understanding of Navier-Stokes Equations and construct appropriate boundary conditions for predicting turbulent fluid flow behaviour.

* Bloom’s Level 6*

3. Determine practical application of CFD in industrial systems and other technologies

* Bloom’s Level 5*

4. Apply discretization techniques to solve Fluid dynamic transport equations to synthesise solutions for fluid flow problems using CFD and compare with experimental data.
