Investigation of Flow Separation Over NACA 24015 and 24021 Airfoils using Flow Injection Method

Abstract

Few explorations used different stream control techniques to work on the streamlined presentation of different airfoils by postponing the stream partition. In this paper, a complete investigation of NACA 24015 and NACA 24021 airfoils was done in CFD at different approaches for various free stream speeds. CATIA V5 R20 was utilized to make the 2D model of the airfoils and the SST K-e disturbance model was used for CFD investigation. Full investigation is performed on a typical airfoil to comprehend the stream conduct at different point of assaults and admission speeds and the equivalent is accomplished for vented airfoils also by concentrating on the suitability of the log jam surrendering approach.

Enhancing Flow Separation Control Using Hybrid Passive and Active Actuators in a Matrix Configuration

“…Reducing flow separation and recirculation in this simplified model holds significant implications for industrial flow applications. The potential of passive devices such as vortex generators [41][42][43] and active devices such as microjet actuators [44][45][46][47][48][49] to the effective ramp separation control have been successfully demonstrated in the state-ofthe-art experiments and numerical simulations. The current research adopts a smooth backward-facing ramp profile initially proposed in [40].…”
