Drag reduction

Drag reduction

Drag generated during the motion of bodies in a fluid constitutes a major source of energy loss. In various sectors, including transportation, logistics, aviation, and marine industries, drag reduction directly contributes to lowering fuel consumption and enhancing operational efficiency. Moreover, drag-reduction technologies play a significant role in mitigating greenhouse gas emissions, thereby promoting environmental sustainability. The benefits of drag reduction become particularly pronounced under conditions of high-speed travel or long-distance transportation. Accordingly, drag reduction represents a critical technological challenge with both economic and environmental implications.

1. Cargo vehicle drag reduction

2. Considerable drag reduction and fuel saving of a tractor–trailer using additive aerodynamic devices

3. Substantial drag reduction of a tractor-trailer vehicle using gap fairings

4. Bio-inspired cab-roof fairing of heavy vehicles for enhancing drag reduction and driving stability
