“…Experimental analysis conducted by Yamada et al (2019) in a low-speed tunnel at a free stream velocity of 18m/s indicated that the use of gurney flaps on the BWB configurations generated a pair of counter-rotating vortices and also improved the lift locally. Several BWBs under the prototyping stage are reported by Thompson et al (2011), Becker and Sheffler (2016), Rodzewicz et al (2018), Footohi et al (2019), Naeini et al (2019Naeini et al ( , 2021) and many others.…”

With the advancement in the modern transport system, it has become imperative to achieve larger aircraft volume at minimum cost wherein aerodynamics plays a major role. The present work aims to investigate the flow over a typical blended wing body (BWB) configuration at different angles of attack adopting experimental and computational techniques. Experiments consisted of the force measurements and oil flow visualizations at a free stream velocity of around 19 m/s. Computations were made using the commercially available software ANSYS 18.1. Results indicated that the use of a Blended Wing Body Configuration resulted in improved aerodynamic characteristics in comparison to other wing configurations such as Delta/ Double delta wings. Surface flow visualization carried out over the BWB configuration indicated the reason behind increased lift coefficients. Reasonable agreement of experiments and computations was observed.

Experiments and computations were made on a blended wing body at a free stream velocity of 18 m/s and at different AoA. Experiments consisted of flow visualizations using oil and tuft flow techniques. Computations were made using the commercial software ANSYS Fluent. Results indicated a highly complex flow behavior in the leeward side of the blended wing body. Reasonable agreement between experiments and computations was observed.
