Early car aerodynamic development focused on physical observation rather than simulation. Wind tunnels were first developed ...

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

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 ...

The 1970s marked the three-box sedan era’s peak, but the decade’s pressures were pushing automakers toward an aerodynamic shift. Factors like the 1970s fuel crisis and increased highway speeds ...

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model the flow of air around the object by ...

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 ...

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 ...

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 ...

A research team has demonstrated a unique method that reduces the aerodynamic resistance of ships by 7.5 per cent. This opens the way for large cargo ships borne across the oceans by wind alone, as ...
