Calculate y+ – Estimate initial cell height
Knowing how to calculate y+ is very important when using turbulence modelling. To obtain an initial cell height above the wall (aerofoil surface, for example), one can calculate an approximate height using the following method. The following assumptions are made,
- The gas is ideal
- A zero-pressure gradient is assumed
The non-dimensional wall distance, y+ is given by, Continue reading
What is Aerodynamics?
Aerodynamics is a very broad subject in aerospace engineering, which generally focuses on the movement of fluid. In aerodynamics, the word, fluid, means liquid or gas. There is no hard and fast definition of aerodynamics, but rather the generalisation that aerodynamicists are fluid flow engineers. Continue reading

Preparing a Conference Paper
I have been writing a little less on my website recently as I have been preparing a conference paper for presentation at the end of the month. Actually, I’m writing two of them, so twice the workload, twice the stress – twice the reward, I guess. Any academic will be required to, or should at some stage in their career, attend a conference and make a presentation on their work. Continue reading
Lecturing to Undergraduates Effectively
Lecturing to undergraduates presents many challenges to any seasoned academic, industrial presenter or teacher. Whilst all of the undergraduates in your class will have achieved a particular standard of education to have earned a university place, their individual abilities for particular subjects can be quite varied. Many subjects at university bring together a number of skills that the students will have learned at secondary school. However, the art of lecturing is demonstrating successfully how the skills they have learned can be applied. Continue reading
Delivering a lecture/presentation
The majority of people in work nowadays will probably have delivered a presentation at some point of their career. Beyond the world of work, I can guarantee that many students at primary, secondary and tertiary level education will have delivered a presentation at some point. In the past few years, I have done more presentations that I care to remember. In my current role I have a presentation to give every three months. Continue reading
Surviving a PhD – Why go to conferences?
At some point throughout your research you will be either required, or requested (by your supervisor) to attend, or even present your research, at a conference. But why do organisations arrange conferences? What are the benefits of attending? Here I discuss why conference attendance is a very important part to being a successful researcher. Continue reading
