The diffuser has been an area exploited by the Red Bull team over recent seasons with them exploring the use of blowing it's outer edges (2010-11 Exhaust Blown Diffuser and 2012-13 'Coanda' exhausts). With this practice curtailed in 2014 by the centreline placement of a single exhaust outlet it's no surprise to see changes in this area.


For Melbourne the team have revised the inner vertical strakes, adding slots to the lower section of the elements, the strakes also feature a more aggressive curvature ahead of the slots which will manipulate the way in which the air flows around them. The strakes purpose is to aid the diffuser in yaw, creating pockets for the airflow to collate, maximizing the performance of the diffuser in its entirety. The slots will allow airflow to bleed off under rotation, further maximizing the pressure gradients at play.


During pre-season the team have also been utilising some small Vortex Generators at the transition between the flat section of floor that houses the plank and the upward curvature of the Diffuser.  These were used in Melbourne and are a likely response to the loss of the starter motor hole as a way of injecting airflow into the central portion of the Diffuser.  The Vortex Generators will aid in overcoming the sharp transitional incline, allowing the airflow to operate more effectively over a wider speed threshold.

Whilst I'm trying to keep atop of the blog you may have noticed of late that there is less content appearing. For those of you that haven't realised, most of my work has now been moved over to Motorsport.com where I'm working with Giorgio Piola.

I'm still doing the technical image gallery for each GP with the continued support of friend of the site Sutton Images. However, as always my time is limited and so this might not be updated as quickly as it once was, so keep checking back.

As some of you may have found out already I'm also working with the Missed Apex crew on their podcast from time-to-time, either doing race reviews or dedicated 'Tech Time' shows.

I've embedded the latest version of the podcast below and will update this a frequently as I appear. However, please head over to Itunes if you want it to appear in your player when episodes are available. The show is great to work on and has a great lineup of 'regulars' but has also enticed some bigger names recently too, with Will Buxton and Bradley Philpot on shows during the summer break.
