New aerodynamic simulator will assist HGV efficiency

A web-based system that simulates aerodynamic efficiency of HGVs is being developed with funding support from the Department for Transport (DfT).

TotalSim’s Computational Fluid Dynamics (CFD) package, known as ACT (Aerodynamic Configurator for Transport), is part-supported by the DfT’s Low Emissions Freight and Logistics Trial, which has awarded a grant of £392,240 towards the total £560,342 project costs.

ACT will enable fleet managers to select the most efficient configuration of truck and trailer for an operation. It will assess the shape of vehicles and trailers and their combinations for aerodynamic efficiency under a range of conditions.

TotalSim’s Managing Director, Rob Lewis, said, “Using CFD, we can simulate the aerodynamic efficiency of any vehicle – usually to help make racing cars go faster – but in this instance we are interested in increasing fuel efficiency to reduce HGV emissions.”

“Transport operators of all technical abilities can try out different configurations quickly and easily in order to deploy the most efficient cabs and trailers. This will dramatically reduce journey costs and greenhouse gas emissions alike.”

Combined with telematics data, ACT can also be used for route and weather-specific planning decisions.

TotalSim will partner with fuel-saving analytics firm Dynamon whilst trialling the system.

Dynamon’s CEO, Angus Webb, said, “TotalSim will identify the best aerodynamic shapes and Dynamon will use fleet telematics data to identify the potential fuel saving and ROI. This will both improve investment in aerodynamics by fleets and stimulate innovation from aerodynamics suppliers.”
