Aerodynamic Analysis in CFD for the Economics of Speed

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.
FORMULA ONE Rear Wings: a very specific video.

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.
Bonnet Vents: On The Search for Front Downforce

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.

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...

Aerodynamics of a Camper Trailer Through CFD
Просмотров 10 тыс.Год назад
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...
Hatchback Aerodynamics: Improving the rear wing or spoiler

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...
Wheel Arch Modifications

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.

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.

Since the mid nineties the aerodynamics of the suspension was more related to drag reduction. However the Tyrrell 024 represented a step change in thinking. From then on the front suspension was considered more and more important for its aerodynamic function and less so for its vehicle dynamics. This video analyses how much the role of aerodynamic bodywork over the actual suspension arms has on...

    Does anyone who has the skill and knowledge and access to the necessary software etc have the desire to apply their skill and knowledge to a real world race car 'for enjoyment' ? I run a car in a championship in the UK where bodywork design is completely free and I would really like to improve the aerodynamics of my car.

    Then why do not only open the top front aera with vents? Maybe i'm wrong but a think it could suck the hot air before reaching the engine and reduce lift because no aera to lift?

  • @jcon6115

    Convex trailing surfaces tend to have vorticity attached to them which helps them with streamlining. It's hard to use concave shapes to guide flow, it will look like crap on most cars having U or C shapes on the top body work. Alternatively those convex shapes are flow killers in the underbody.

    Very nice, Nelson. I appreciate the effort you went into in order to avoid using "big" and "scary" equations to describe the underlying physics, and went for an approach that would be easier to understand for a wider audience instead. I wouldn't mind seeing more of these videos in the future, though I enjoy your more "practical" videos on automotive aerodynamics as well. Either way, keep up the good work!

    Check out the flow structure @ 4:07 behind the rear wheels, in the 'inboard loaded(problematic)' frame. Notice how it's dragging down the rear wing tip wake, swallowing the beam wing tip vortex, and the diffuser corner flow. I think a huge amount of performance is in that region, and that a heavily inboard loaded front wing strengthens the flow structure in the rear wheel because it connects with the upper wheel vortex shed off the front wheel.

    I am trying to overcome the turbulence around my domestic car, to get a laminar flow of air from front to back. This last year I have been going down the 'Rabbit Hole' in every aspect to achieve this Learning on the effectiveness of a 'Under Tray', the effectiveness of 'Air-Curtains', 'Hood Ducting', 'Separation Edging', Adding a Lower 'Air-Dam' and blocking off the upper part of the grille to improve the aerodynamics and reduce the drag. Not having the Computer Capacity or Finances to research the CFD of my car I like to see if someone can do some tests to see he effectiveness of each of these as well as the effects of a Car-Bra, Bug-Shield, and other Add-Ons for the domestic car market.
