Early car aerodynamic development focused on physical observation rather than simulation. Wind tunnels were first developed for aviation during the 1870s and were used by pioneers such as the Wright ...

Engineers from Lawrence Livermore National Laboratory (LLNL) have proposed reshaping heavy vehicles such as semi-trucks to be more aerodynamic. This new continuous design could significantly reduce ...

Aerodynamic design optimization has evolved into a mature discipline that integrates computational fluid dynamics, sensitivity analysis and optimisation algorithms to refine shapes and configurations ...

With additive manufacturing, used to build this heat exchanger, one key is to do prototyping for the part and then see whether additive or subtractive manufacturing is the better choice of manufacture ...

Automakers and car designers had been toying with aerodynamics long before the 1970s rolled around. Notable exploits from the earlier days include the slippery teardrop-shaped Tatra and the ...

For much of the twentieth century, the automobile was shaped less by the wind than by the whims of stylists and the desires of buyers. Long before drag coefficients became a selling point, car bodies ...

This figure shows the comparison of the spatial distributions of the time-averaged flow field before and after drooping the leading edge in the form of u-velocity sections. With the drooping leading ...

Advanced studies in aerodynamics may spark a shift in streamliner design. Flat out land speed racing is a whole different world requiring special attention to the subject of aerodynamics to be a ...

The Indian Space Research Organisation (ISRO) has developed Computational Fluid Dynamics (CFD) software named Parallel RANS Solver for Aerospace Vehicle Aero-thermo-dynamic Analysis (PraVaHa). This ...

Formula 1's sleek racing machines look so different to the cars we see every day on the road because their design is dictated by aerodynamics. This is the study of forces and their impact on how ...

Regardless of the technological pathways that will be followed in future to develop aircraft with significantly less or no climate impact, the most important factors are reducing drag and weight, as ...
