Computational Fluid Dynamics (CFD) is a superb device, permitting aerodynamicists a option to visualize and optimize airflow in a method inconceivable in the true world. It can be used for sillier goals. Like evaluating the aerodynamics of a 40-series Toyota Land Cruiser to a loaf of bread. 

We have all the time joked about this type of factor, however YouTube channel Premier Aerodynamics truly went and did it. And shockingly—or, possibly not—the bread truly wins. The bread’s 0.57 drag coefficient is not nice, however it beats the Land Cruiser’s 0.66. Moreover, the Land Cruiser generates about 52 kilos of elevate at 45 mph, the bread generates nearly none. The way you speed up bread to 45 mph is as much as your ingenuity. 

The rounded profile of the highest of the bread loaf helps airflow keep hooked up alongside its size, minimizing the wake on the rear. The flatter backside of the bread is not fairly so good, so that you get some air detaching, however the video host notes that you possibly can enhance this by rounding off the sharp nook of this explicit loaf. Clearly (?) the bread has a big frontal space, although, so there’s a whole lot of air hitting it, which is why it is considerably draggy.

The large downside with the Land Cruiser is, effectively, it is a tall, sq. truck with large wheels and plenty of uncovered mechanical elements beneath. Its very nature is what makes it so compromised. After all, the 40-series Land Cruiser was by no means meant to be some type of streamliner: It was meant to be a troublesome off-roader, and that it’s. It would not matter that its aero is… worse than a loaf of bread. However it’s humorous.
