A Comparative Study of Energy Models for Turkish Electricity Market Using LEAP
Massaga, Daniel Julius; Kirkil, Gökhan; Çelebi, Emre (IEEE Computer Society, 2019)Fossil fuel thermal power plants constitute a large part of the Turkish electricity generation capacity. Turkish government has been developing several energy policy documents to evaluate how various renewable energy sources ... -
Detached eddy simulation of shallow mixing layer development between parallel streams
Kirkil, Gökhan (Elsevier Science Bv, 2015)Results of a high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel with a smooth flat bed and medium ... -
Development of a parallel 3D navier–stokes solver for sediment transport calculations in channels
Kirkil, Gökhan (MDPI AG, 2020)We propose a method to parallelize a 3D incompressible Navier–Stokes solver that uses a fully implicit fractional-step method to simulate sediment transport in prismatic channels. The governing equations are transformed ... -
Effects of cylinder Reynolds number on the turbulent horseshoe vortex system and near wake of a surface-mounted circular cylinder
Kirkil, Gökhan; Constantinescu, George (Amer Inst Physics, 2015)The turbulent horseshoe vortex (HV) system and the near-wake flow past a circular cylinder mounted on a flat bed in an open channel are investigated based on the results of eddy-resolving simulations and supporting flow ... -
Flow and Turbulence Structure Around an In-Stream Rectangular Cylinder with Scour Hole
Kirkil, Gökhan; Constantinescu, George (TSINGHUA UNIV, 2013)An eddy resolving technique is used to reveal the unsteady dynamics of the coherent structures present in the flow field around an in-stream vertical cylinder with a scour hole at a channel Reynolds number of 240000. Such ... -
Flow Structure in a Shallow Mixing Layer Developing over 2-D Dunes
Kirkil, Gökhan (E D P Sciences, 2018)A high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel over two-dimensional (2D) dunes. The study ... -
A framework for water and carbon footprint analysis of national electricity production scenarios
Shaikh, Mohammad A.; Küçükvar, Murat; Onat, Nuri Cihat; Kirkil, Gökhan (Pergamon-Elsevier Science Ltd, 2017)While carbon footprint reduction potential and energy security aspects of renewable and non-renewable resources are widely considered in energy policy their effects on water resources are mostly overlooked. This research ... -
Large Eddy Simulation of Wind Flow over A Realistic Urban Area
Kirkil, Gökhan; Lin, Ching-Long (MDPI, 2020)A high-resolution large eddy simulation (LES) of wind flow over the Oklahoma City downtown area was performed to explain the effect of the building height on wind flow over the city. Wind flow over cities is vital for ... -
Modeling of Wind Effects on Stratified Flows in Open Channels: A Model for the Istanbul Strait (Bosphorus)
Stratified flows in open channels arise as a result of density or surface level differences. If the channel is connected to a basin at one or both ends, strong winds originating from the basin cause the "wind setup" effect ... -
A Numerical Study of Shallow Mixing Development over Flat Surface and Dunes
Kirkil, Gökhan; Constantinescu, George (TSINGHUA UNIV, 2013)Results of a high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel with a smooth flat bed and dunes. ... -
A numerical study of the laminar necklace vortex system and its effect on the wake for a circular cylinder
Kirkil, Gökhan; Constantinescu, George (Amer Inst Physics, 2012)Large eddy simulation (LES) is used to investigate the structure of the laminar horseshoe vortex (HV) system and the dynamics of the necklace vortices as they fold around the base of a circular cylinder mounted on the flat ... -
Resolved turbulence characteristics in large-eddy simulations nested within mesoscale simulations using the weather research and forecasting model
Mirocha, Jeff; Kosovic, Branko; Kirkil, Gökhan (2014)One-way concurrent nesting within the Weather Research and Forecasting Model (WRF) is examined for conducting large-eddy simulations (LES) nested within mesoscale simulations. Wind speed spectra and resolved turbulent ... -
Transition and equilibration of neutral atmospheric boundary layer flow in one-way nested large-eddy simulations using the weather research and forecasting model
The Weather Research and Forecasting Model permits finescale large-eddy simulations (LES) to be nested within coarser simulations an approach that can generatemore accurate turbulence statistics and improve other aspects ... -
Turkish public preferences for energy
Ediger, Volkan S.; Kirkil, Gökhan; Çelebi, Emre; Ucal, Meltem Şengün; Kentmen-Cin, Çiğdem (Elsevier Science, 2018)Public concern over energy supplies prices sustainability and efficiency has emerged as a major issue around the world. Yet most of what we know regarding public opinion on energy comes from North America and Europe. This ...
