flow field investigation of a blended wing body in low speeds

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.
