Case study – Vortex generators on Road Train

This trial sought to further quantify the fuel efficiency benefit of an aftermarket device (Airtabs™) fitted to reduce aerodynamic drag. The trial was conducted for one B-double tanker running a regional collection and delivery run in South East Queensland.
The Green Truck Partnership is designed to be a forum for the objective evaluation of the merits of clean vehicle technologies and fuels used by heavy vehicle operators. This report discusses the fourth trial of vortex generating aerodynamic devices. The device was fitted to a B-double tanker in 2016 and monitored for 7 months and over 30,000km (baseline + trial).
