The drivAer model was built for the purpose of aerodynamic validation from windtunnel data to CFD. This video is an introduction of this model through running the fastback, notchback and estate versions. It also is a look at how errors a expressed in this type of experimentation.

Introduction to transient CFD simulations using LES. This video aims to give a guide to how LES simulations can be used to analyse fluid. As opposed to steady state simulation they offer a greater depth of understanding at significant computational cost.

This video focusses on removing the front lift caused by the shape of the bonnets leading edge. In total about 80% improvement in front downforce.

Aerodynamic drag cost power at the cube of velocity. Lowering drag means that traveling at a certain speed will cost less in almost every way. Cars and vehicles that everybody drives aren't optimised to lower the cost of speed. This video analyses the influences that aesthetic cost of speed that is apparent when participating in the consumer car market.

The rear wing since the new regulations set was introduced has been an area which there has been a significant amount of diversity. Particularly around the junction between the main plain and second element. This CFD analysis focuses on this junction area pulling out the main themes and extracting surface forces.

A basic outline of the CFD problem space for venting he engine bay with bonnet vents. It turns out that for a production car using the Super Touring solution of corner vents are a better. However The bonnet vents are directly ducted to the radiator. This would be the next attempt at a solution to provide more downforce for this hillclimb model.

The Meyers Manx Dune Buggy shaped popular culture bridging the divide between the urban and the offroad. Applying boat building technology in the fibreglass body it was a lightweight car that offer surprising performance from a 40hp VW engine. This CFD analysis of its aerodynamics paint a story that I found necessary to improve.

After change the radiator to a more accurate geometry basic floor modification were made. The result was a decent increase in downforce. The openFoam simulation series is a continuation of a Hillclimb aerodynamics build. At this stage is is a has a cla = -0.3, but it is is starting from a body shape that has a high lift value. This Mk1/Mk2 Golf GTi has a generally bad aerodynamic characteristic...

Pushing the concept of a wing on a hatchback a little further. It just confirms that this a robust concept capable of producing a decent amount of downforce.

Something a bit different. Following of from my hatchback model studies in CFD, this camper trailer suffered from a similar characteristic. At the rear there is significant drag caused by the lift through the idea of induced drag. Placing a flap or spoiler at the rear reduced the drag by a large 13%. Further modifications managed to produce a drag reduction of 30-35%. There is probably a little...

This video further developments the Golf GTi's aerodynamics by adding a rear element that increase the downforce for a wing. This video contributes to the understanding of hatchback aerodynamics that the general public lack. Rear wings aren't by themselves a great idea for hatchbacks because they aren't supplied with sufficient clean air flow. Adding a spoiler under the wing dramatically increa...

Using the Golf GTi mkII model the extract wheel arches where modified to increase downforce. The aerodynamic performance increase was modest but there. Changes were most because the extra wide wheel arches, due to Hillclimb modification, removing lift. Addition benefits can from reducing the interaction between the bonnet or hood and the side of thecar.

Using a common 1980's hatchback, this video will first of a series analysing the aerodynamics of cars seen on the European hillclimb scene. The model as a baseline is remarkably poor with a lift to drag ratio of positive one.

Taking images of the cars suspended by the cranes at Monaco the Centre of Gravity, CoG can be found. The Mercedes is a particularly good candidate for this as the angle in which it hung was relatively high. If the angle was lower, like all the other teams, a line intersecting the CoG would have a small horizontal component. With the angle of the Mercedes above 30 degrees it has a reasonable hor...
