Ahead of the rear wheels is quite a crucial zone especially with the teams having lost the ability to seal the diffusers edge with exhaust energy this season. The tyre itself creates turbulent airflow that can impinge on the diffuser, something we call 'Tyre Squirt'. Even with exhaust blown diffusers a plethora of solutions to this problem were used up and down the grid last season with vertical strakes and slots being the order of the day. 


Having already utilised a singular curved strake and multiple floor slots on the W04 the team have clearly continued to evaluate the region. Red Bull ran with a twin strake arrangement and multiple slots for much of last year on the RB9 a configuration that we now see being tried on the W05. Flanked by sections of metal in order to reinforce the floor and stop it from flexing the strakes and slots work in combination to create vortices that try to prevent the incursion of airflow into the diffusers path by 'tyre squirt'. The length and orientation of each of these strakes and slots is carefully designed by the team in order to make them work over a wider operating window / 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.
