Vehicle-induced pressure on divider in isolate and tandem

Roadways provide access and mobility, connecting people in different places. Turbulence induced by moving vehicles on roadways can be potentially used as an energy source. Previous studies have focused on the aerodynamic behaviour of moving vehicles whilst the impact of vehicle-induced turbulence on highway has not been explored. The aim of this study is to investigate the pressure induced by moving cars on the highway divider. Both experimental work and simulation studies were conducted to compare the pressure induced on the divider. Single car (isolate) and car in tandem settings were taken into consideration for this study. The study found that the pressure induced on the highway divider varies with car speed, for both isolate and tandem settings. However, different settings gave slight differences on the pressure induced. The numerical studies conducted verified the experimental data collected. The fluid power induced is theoretically calculated as 303.56W and 275.21W for both isolate and tandem settings respectively.
