Vortex formation in the head pond of a hydroelectric power plant has been studied experimentally in a scaled hydraulic model. Velocity vector field and the turbulent kinetic energy distributions were measured using an Acoustic Doppler Velocimetry (ADV). Free surface flow in the head pond was also simulated using Flow-3D software. Comparison of measured and computed flow variables were satisfactorily good, promising the use of CFD tool to identify surface vortex and calculate its strength from the numerical solution. Vortex strength was evaluated numerically and then it was shown that it can be used as a key parameter to investigate the performance of a given head pond design.

Design and analysis of a vertical axis water turbine for river applications using computational fluid dynamics Demircan, Eren; Aksel, Mehmet Haluk; Pınarcıoğlu, Mehmet Melih; Department of Mechanical Engineering (2014) The main purpose of this study is to design a Darrieus rotor type vertical axis water turbine using Computational Fluid Dynamics (CFD) in order to be used in river currents. The CFD modeling is based on two dimensional numerical solution of the rotor motion using commercial Unsteady Reynolds Averaged Navier-Stokes solvers, Ansys Fluent and CFX. To validate the two dimensional numerical solution, an experimental Darrieus rotor type water turbine from literature is studied and performance of several turbulenc...
Experimental and numerical investigation of the energy harvesting flexible flag in the wake of a bluff body Latif, Usman; Abdullah, Chaudary; Uddin, Emad; Younis, M. Yamin; Sajid, Muhamad; Shah, Samiur Rehman; Mubasha, Aamir (2018-05-01) Inspired by the energy harvesting eel, a flexible flag behind a D-shape cylinder in a uniform viscous flow was simulated by using the immersed boundary method (IBM) along with low-speed wind tunnel experimentation. The flag in the wake of the cylinder was strongly influenced by the vortices shed from the upstream cylinder under the vortex-vortex and vortex-body interactions. Geometric and flow parameters were optimized for the flexible flag subjected to passive flapping. The influence of length and bending ...
Experimental and numerical investigation of a counter-rotating boundary layer ingesting propulsion system Bilyaz, İbrahim Soner; Başkan Perçin, Özge; Department of Aerospace Engineering (2023-1-23) This study investigates the performance of a boundary layer ingesting (BLI) propulsion system with a counter-rotating propulsor numerically and experimentally. The main benefit driver for a BLI propulsion system is that the propulsor ingests the boundary layer of the aircraft's fuselage, which is slower than the free stream velocity and consumes less power to generate the required thrust. The power-saving coefficient (PSC), the amount of power saved to obtain the same net streamwise force compared to the tr...
Improved combustion model of boron particles for ducted rocket combustion chambers Kalpakli, Bora; Acar, Emir Bedig; Ulaş, Abdullah (Elsevier BV, 2017-5) A combustion model of boron particles for detailed Computational Fluid Dynamics (CFD) based simulations of ducted rocket combustion chambers is studied. It is aimed to construct a model for combustion of boron containing gas mixtures ejected from a solid propellant gas generator. This model includes all main physical processes required to define an accurate particle combustion simulation. The reaction rate modeling in similar, previous studies are improved for ramjet combustion chambers and this model provi...
PREDICTION OF SEISMIC ENERGY-DISSIPATION IN SDOF SYSTEMS NURTUG, A; Sucuoğlu, Haluk (Wiley, 1995-09-01) A simple analytical procedure is developed for calculating the seismic energy dissipated by a linear SDOF system under an earthquake ground excitation. The ground excitation is specified by its pseudo-velocity spectra and effective duration whereas the SDOF system is defined by its natural period of vibration and viscous damping ratio. However, the derived relationship for the energy dissipation demand under an earthquake excitation is sensitive neither to the viscous damping ratio nor the ductility ratio w...
