“…Wing-fuselage combinations were studied with thin-layer Navier-Stokes flow solvers by Fujii and Obayashi [58], Vatsa and Wedan [80], and with thin-layer and slender-layer NavierStokes formulations by Deese and Agarwal [55]. Flow solutions presented by Fujii and Obayashi [58] showed the significant influence of the fuselage on the flowfield, especially in the vicinity of the wing root at high angle of attack.…”

In transonic flow, the aerodynamic interference that occurs on a strut-braced wing airplane, pylons, and other applications is significant. The purpose of this work is to provide relationships to estimate the interference drag of wing-strut, wing-pylon, and wing-body ar- his office, leaving with more answers than questions. I also appreciate the fact that he has always had a friendly attitude towards me. I have enjoyed interacting with Dr. Kapania, whose cheerful attitude and perpective on life and research is very similar to mine. I would like to acknowledge the contribution of Dr. Grossman to the team in the field of numerical calculations and his desire of improving the life of the graduate students by forming the Graduate Advisory Committee. Dr. Raj deserves a lot of thanks for providing me with useful advice throughout this project despite his busy schedule. I appreciate the fact that he has always been interested in knowing more about the evolution of my research work and career. The "virtual" presence of Dr. Haftka during our weekly meetings has been very beneficial because of his ability to foresee difficulties and to get the team members to not lose sight of the big picture.

“…Besides these the wings of a complete aircraft experience interference effects of the fuselage and jet engine nacelles. Again the field solutions using Navier-Stokes and Euler equations are well suited to study these effects (Chaussee 1986;Deese & Agarwal 1987;Volpe & Jameson 1988;Radespiel 1989;Rossow & Ronzheimer 1991;Rudmik 1991;Longo 1992;Rossow et al 1992;Wichmann 1992).…”

“…The outer parts of the blades operating at transonic speeds need to have supercritical aerofoil-shapes, as they are involved in producing supersonic zones and shock waves. Recent investigations (Bober et al 1983;Deese & Agarwal 1988;Kroll 1989) report the advancements in numerical aerodynamics.…”

The mathematical physics of fluid flow in a compressible medium, leads to nonlinear partial differential equations or their equivalent integral versions. For the solution of these equations one has generally to resort to numerical methods using mostly finite difference or finite volume schemes, which are well established now. These field methods are very suitable for studying the physical features of complex flows. The present paper gives at first a short sketch of the numerical procedure and thereafter goes into the detailed analysis of the flow fields of delta wings, double-delta wings, delta shaped wing-canard combinations and space vehicles. Further examples include long span wings and wing-bodies at supercritical on flows, flows around propellers and rotors and finally some unsteady flows. The examples cited are selected topics from the extensive studies undertaken in the department of numerical aerodynamics of the DLR in Braunschweig in the course of the last few years.
