Abstract
This numerical study, based on steady RANS simulations, investigates the effects of passive, active, and combined flow control techniques on a simplified vehicle model (Ahmed body) under highway-relevant configurations, including platooning and overtaking, at 70 mph (31.3 m/s). The study primarily focuses on an innovative passive flow control method, Rear Linking Tunnels (RLTs), previously introduced by the authors. It also examines the performance of the Single Dielectric Barrier Discharge Actuator (SDBD) as an active flow control strategy and evaluates its combined effects with RLTs on both the target vehicle and surrounding vehicles during platooning and overtaking maneuvers. The results highlight notable variations in drag and lift coefficients, showing that the effectiveness of these flow control methods differs significantly between platooning/overtaking scenarios and single-vehicle cases.
期刊介绍:
Flow, Turbulence and Combustion provides a global forum for the publication of original and innovative research results that contribute to the solution of fundamental and applied problems encountered in single-phase, multi-phase and reacting flows, in both idealized and real systems. The scope of coverage encompasses topics in fluid dynamics, scalar transport, multi-physics interactions and flow control. From time to time the journal publishes Special or Theme Issues featuring invited articles.
Contributions may report research that falls within the broad spectrum of analytical, computational and experimental methods. This includes research conducted in academia, industry and a variety of environmental and geophysical sectors. Turbulence, transition and associated phenomena are expected to play a significant role in the majority of studies reported, although non-turbulent flows, typical of those in micro-devices, would be regarded as falling within the scope covered. The emphasis is on originality, timeliness, quality and thematic fit, as exemplified by the title of the journal and the qualifications described above. Relevance to real-world problems and industrial applications are regarded as strengths.
