Numerical simulation of transverse side jet interaction with supersonic free stream
G. Aswin,Debasis Chakraborty +1 more
TL;DR: In this paper, the interference effects of side jets with supersonic cross flow for a lateral jet controlled missile are simulated numerically using a commercial CFD software and a very good agreement between computed and experimental surface pressure has been obtained.

A General Framework for the Optimal Control of Unsteady Flows with Applications
TL;DR: In this article, the authors present a general framework to derive a discrete adjoint method for the optimal control of unsteady flows and demonstrate the application of the theory to one-and two-dimensional inverse pulseshape designs, the data assimilation problem in a shock-tube, the drag minimization of viscous flow around a rotating cylinder, and the remote inverse design of a turbulent flow around NACA0012 airfoil at a high angle of attack.
Fluid mechanics, turbulent flow and turbulence modeling
TL;DR: This course material was used in two courses in the Internatio l Master's program of applied mechanics at Chalmers as discussed by the authors, TME225 Mechanics of fluids, and MTF270 Turbulence Modeling.

Airbus, ONERA, and DLR Results from the Second AIAA Drag Prediction Workshop
TL;DR: The results from DLR, Airbus, and ONERA from the Second AIAA Computational Fluid Dynamics Drag Prediction Workshop are presented in this paper, where the lift, drag, and pitching moments are calculated for the DLR-F6 configuration at transonic flow conditions by solving the Reynolds-averaged Navier-Stokes equations on structured as well as on unstructured, hybrid grids.

Progress in the numerical analysis of compact heat exchanger surfaces
TL;DR: In this article, the authors provide a comprehensive review on numerical studies of single-phase velocity and temperature fields, and heat transfer and flow friction characteristics of compact heat exchanger surfaces, and also provide specific comparisons to evaluate the accuracy of numerical work where experimental data are available.

Reassessment of the scale-determining equation for advanced turbulence models
TL;DR: In this paper, a two-equation turbulence model is proposed that is shown to be quite accurate for attached boundary layers in adverse pressure gradient, compressible boundary layers, and free shear flows.

Direct simulation of a turbulent boundary layer up to R sub theta = 1410
TL;DR: In this paper, the turbulent boundary layer on a flat plate, with zero pressure gradient, is simulated numerically at four stations between R sub theta = 225 and R sub tta = 1410.

A mathematically simple turbulence closure model for attached and separated turbulent boundary layers
D. A. Johnson,L. S. King +1 more
TL;DR: In this article, a new turbulence closure model was proposed to treat two-dimensional, turbulent boundary layers with strong adverse pressure gradients and attendant separation by using an ordinary differential equation derived from the turbulent kinetic energy equation to describe the stream wise development of the maximum Reynolds shear stress in conjunction with an assumed eddy viscosity distribution.

R. C. Swanson,Eli Turkel +1 more
TL;DR: In this paper, an artificial dissipation model, including boundary treatment, that is employed in many central difference schemes for solving the Euler and Navier-Stokes equations is discussed.
