Summary

 

Mathematics - AERO95006

Aims

To ensure that all students acquire the mathematical knowledge and skills required for the second and later years of their aeronautical engineering course.

Role

Lecturer

Hydrodynamic Stability - AERO97054

Aims

Study of laminar-turbulent transition in various fluid flows, and in particular, in the boundary layer on an aircraft wing represents a major branch of modern Fluid Dynamics. The transition takes place due to the fact that at a sufficiently large value of the Reynolds number the flow becomes unstable, in the sense that small perturbations, introduced in the laminar flow due to, say, acoustic noise or free-stream turbulence, are no longer damped by the viscous effects. Instead they start to grow in time, leading to the transition to turbulent state of the flow.  In this lecture course modern mathematical techniques that are used to predict the conditions when the laminar-turbulent transition takes place will be discussed.

Role

Lecturer

Applied Computational Aerodynamics - AERO97051

Aims

  1. The main objective of the course is to develop the engineering skills required for the students to become intelligent users of aerodynamic simulation codes.

The course will concentrate on familiarising students with the key numerical methods utilised for solving the governing equations of fluid dynamics for aerodynamic design. Students will learn the basic numerical and aerodynamic concepts required by using existing open-source and commercial computer programs to simulate and analyse aerodynamic flows. Through the use of project-based learning, via a combination of lectures and practical assignments, the course will build on the students’ prior knowledge of aerodynamics so that they can effectively design, set-up, perform, validate and assess the accuracy of simulations via computational codes.    

The aim of the course is to give students:

(i)         A sufficient body of knowledge and an appreciation of the capabilities and limitations of computational aerodynamics tools for them to become good users.

(ii)        An increase awareness of the computational aerodynamic tools available to them and an ability to choose the right tool for a given analysis and design task.

(iii)      Practical experience in the use of panel codes (Xfoil), vortex-lattice codes (AVL), and common commercial CFD packages (Star-CCM+).

(iv)      Competency in the use and evaluation of computational codes for advanced aerodynamic analysis.
