Figure 1. From racing cars to bobsled racers, aerodynamic shaping is crucial to achieving top speeds. Bobsleds are designed for speed. They are shaped like a bullet with tapered fins. (credit: U.S. Army, via Wikimedia Commons)The value of the drag coefficient, C , is determined ...
Moreover, the GA_XGBoost model also improves predicting accuracy on automobile aerodynamic drag coefficient than other models. The knowledge gained herein not only builds a novel model with satisfactory performance on predicting automobile aerodynamic drag coefficient for the SUV model, but also provides...
Faired-in rear wheels, a tiny frontal area and cameras replacing door mirrors add up to a barely believable drag coefficient of just 0.186Cd, which is less than a paper aeroplane. Only 250 were made, costing £120,000 a piece, while servicing costs are so eye-watering you’d be bette...
in the future, one could access a new design or an existing vessel and pass an intelligent judgment on its behavior in gale force winds. I hold the opinion that the prismatic coefficient, location and shape
This drag coefficient is usefull if you want to compare the aerodynamic design of several cars. From Hucho's book, this drag coefficient is equal to 1.17 for a circular plate, 0.47 for a sphere, 0.42 for half a sphere. This 3 shapes are view as a disc by the flow. Sylvain«...
Throughout the convergence of iterations, the coefficient of the drag value was obtained, and it was noticed that the coefficient of the drag decreased from 0.51 to 0.306 at a velocity of 22 m/s. In addition, the drag was reduced from 22 m/s by generating dimples in the front and back...
The Aurora Vehicle Association (headquartered in Melbourne, Australia) began developing solar cars in 1987 [33]. The drag and rolling resistance coefficients of their 2007 SEV can be seen in Table 6 and Table 7. This is a good starting point for this research as to what the coefficient of ...
perforated road sign;drag coefficient;porosity;wind speed 1. Introduction Under abnormal weather conditions, such as strong gusts of wind, induced by natural phenomena, road facilities, such as road signs, frequently get damaged. This damage accounts for approximately 8% of all damage to public fac...
