| Abstract | Through its ecoTECHNOLOGY for Vehicle II program, Transport Canada has commissioned a project to investigate the aerodynamic improvements possible with current and emerging drag reduction technologies for heavy-duty vehicles (HDVs), with the intent of guiding future implementation of such technologies for Canada’s transportation industry. The project will consist of wind-tunnel testing of a scale-model HDV with various drag reduction technologies. Progress towards the development of a Flow Treatment System (FTS) for generating winds
experienced by HDVs on the road is presented (Phase 1 - Stream A). This includes the results and analysis of 1) the on-road tests to measure the winds experienced by road vehicles, 2) the small-scale wind tunnel tests to evaluate concepts for simulating the measured winds, 3) the small-scale wind tunnel tests to investigate the sensitivity of HDV drag to turbulence, 4) the intermediate-scale demonstration of the selected concept, and 5) the selection of an appropriate blockage correction method for HDVs in turbulent flow. The project progress to date is described and the required next steps are defined. This report forms a redacted version of the original LTR-AL-2014-0014 for public dissemination. |
