Active flow control (AFC) based on plasma synthetic jet actuator (PSJA) has been attracted a lot of researchers since Anderson and Knight put forward the concept PSJA for first time. Since then characteristic studied by means many numerical simulations experiments. This article showed series studies that manipulated vehicle without moving surfaces. Firstly, we research characteristics aviation ...

Aerodynamic drag reduction is required with new stringent constraints on pollutant emissions and fuel efficiency of ground vehicles. In this context, active flow control a promising approach to achieve target. This study focuses applying different strategies the square-back Ahmed model reduce aerodynamic drag. A steady blowing jet, synthetic jet an unsteady are located at back edges as devices....

Abstract

The use of a chevron nozzle/orifice is one the methods heat transfer enhancement and noise reduction. In case synthetic jets, number papers on this topic small. Therefore, jet actuator with three different orifices circular orifice investigated. aim study to find impact shape centerline velocity (measured hot-wire anemometer) determine if reduces generated noise. sound pressure level was strong...
