Dynamic Transition From Regular to Mach Reflection Over a Moving Wedge
Lubna Margha, Ahmed A. Hamada, Doyle D. Knight +1
The transition between the Regular Reflection (RR) and Mach Reflection (MR) phenomenon impacts the design of the supersonic and hypersonic air-breathing vehicles. The aim of this p…
Numerical Investigation of a Rotating Double Compression Ramp Intake
Lubna Margha, Ahmed A. Hamada, Othman Ahmed +1
The intakes of air-breathing high-speed flying vehicles produce a large share of the thrust propulsion. Furthermore, the propulsion performance of these engines increases when the…
Dynamic Transition From Mach to Regular Reflection Over a Moving Wedge
Lubna Margha, Ahmed A. Hamada, Ahmed Eltaweel
The design of supersonic and hypersonic air-breathing vehicles is influenced by the transition between the Mach Reflection (MR) and Regular Reflection (RR) phenomena. The purpose o…
Shock System Dynamics of a Morphing Bump Over a Flat Plate
Ahmed A. Hamada, Lubna Margha, Mohamed M. AbdelRahman +1
In this paper, the shock dynamics due to the movement of a bump over a flat plate flying at supersonic speed are numerically investigated. The bump is located at the impingement po…
Development of a Finite Element Solver Including a Level-Set Method for Modeling Hydrokinetic Turbines
Ahmed A. Hamada, Mirjam Fürth
Hydrokinetic flapping foil turbines in swing-arm mode have gained considerable interest in recent years because of their enhanced capability to extract power, and improved efficien…
Variants of the Finite Element Method for the Parabolic Heat Equation: Comparative Numerical Study
Ahmed A. Hamada, Mahmoud Ayyad, Amr Guaily
Different variants of the method of weighted residual finite element method are used to get a solution for the parabolic heat equation, which is considered to be the model equation…
