Computational Fluid Dynamics Modeling of Pipe Eccentricity Effect on Flow Characteristics of Newtonian and Non-Newtonian Fluids
SORGUN, MEHMET (Informa UK Limited, 2011-01-01)
The prediction of accurate drilling fluids behavior inside an annulus is especially important in drilling engineering during hydraulic program design. The flow characteristics of Newtonian and non-Newtonian fluids drastically change in the annuli when the inner pipe is eccentric. In this study, the fluid flow inside concentric, partially eccentric, and fully eccentric annuli are modeled using computational fluid dynamics. Computational fluid dynamics simulations are performed to investigate the effect of pi...
Computational fluid dynamics analysis of store seperation
Demir, H. Özgür; Alemdaroğlu, Hüseyin Nafiz; Department of Aerospace Engineering (2004)
In this thesis, store separation from two different configurations are solved using computational methods. Two different commercially available CFD codes; CFD-FASTRAN, an implicit Euler solver, and an unsteady panel method solver USAERO, coupled with integral boundary layer solution procedure are used for the present computations. The computational trajectory results are validated against the available experimental data of a generic wing-pylon-store configuration at Mach 0.95. Major trends of the separation...

Computational fluid dynamics simulations of ship airwake with a hovering helicopter rotor
Orbay, Ezgi; Uzol, Oğuz; Sezer Uzol, Nilay; Department of Aerospace Engineering (2016)
In this thesis, Computational Fluid Dynamic simulations of ship airwake for a simple ship geometry are performed for the horizontal and inclined deck configurations and also with and without the helicopter rotor over the deck. An actuator disk model is used for the CFD simulations of a rotor model hovering over the flight deck. All of the computations are performed by using a commercial finite volume CFD flow solver. The unstructured tetrahedral grids are generated in the computational domain including ship...

Gelisli, Kubra Asena; Aradag, Selin; Tascioglu, Yigit; Özer, Mehmet Bülent (2019-01-01)
© 2019, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.A Computational Fluid Dynamics (CFD) study is conducted to investigate the unsteady, turbulent supersonic cavity flow characteristics and to control the severe effects of the flow field. Simulations of Mach 1.5 supersonic cavity flow with a length to depth ratio of 5.07 are performed using commercial ANSYS Fluent solver. Unsteady density-based Reynolds Averaged Navier-Stokes equations are modeled with standard k-ω turb...
