Analysis of Delta Wing Vortical Substructures Using Detached-eddy Simulation
An understanding of the vortical structures which comprise the vortical flowfield around slender bodies is essential for the development of highly maneuverable and high angle of attack flight. This is primarily due to the physical limits these phenomena impose on aircraft and missile s at extreme flight conditions. Demands for more maneuverable air vehicles have pushed the limits of current CFD...
متن کاملLarge-Eddy Simulation of a Wing–Body Junction Flow
Large-eddy simulations of awing-body junction flow experimentally studied are presented.Wall junction flows are common in engineering applications, but the flow physics at the corners of the junction is not well understood. Moreover, in these types of flows, the performance of the subgrid-scale models frequently used for large-eddy simulations is not well characterized. To address these issues,...
متن کاملDelayed Detached Eddy Simulation of 3-D Wing Flutter with Fully Coupled Fluid-Structural Interaction
This paper presents a strategy using a high fidelity delayed-detached-eddy simulation (DDES) to simulate 3-D fluid-structural interaction for predicting AGARD Wing 445.6 flutter boundary in a transonic flow. A dual-time step implicit unfactored Gauss-Seidel iteration with Roe scheme are employed for the flow solver. The special numerical techniques used herein include: a 5th order WENO scheme f...
متن کاملDetached-eddy Simulation: Current Status and Perspectives
Detached-Eddy Simulation (DES) is a hybrid technique proposed in 1997 as a numerically feasible and plausibly accurate approach for predicting massively separated flows. Since its inception the method has been applied to a range of configurations including simple shapes such as cylinders, spheres and aircraft forebodies, in addition to complex geometries including fighter aircraft. The accuracy...
