Numerical calculation of rough turbulent boundary layer for incompressible fluids
Atay, Görkem; Bayer, Özgür; Çıray, Cahit; Department of Mechanical Engineering (2018)
In this thesis, a numerical code for calculating turbulent boundary layer parameters is developed. Two-dimensional turbulent flow over a rough flat plate with zero pressure gradient is numerically solved by using the integral method. Fluid mechanics formulations, such as momentum integral equation are coupled with the results of Nikuradse’s experiment. Throughout the calculation, turbulent boundary layer parameters, such as boundary layer thickness, displacement thickness, momentum thickness, local skin-fri...
Numerical calculation of backfilling of scour holes
Sumer, B Mutlu; Baykal, Cüneyt; Fuhrman, David R; Jacobsen, Niels G; Fredsoe, Jorgen (2014-12-04)
A fully-coupled hydrodynamic and morphologic CFD model is presented for simulating backfilling processes around structures. The hydrodynamic model is based on Reynolds-averaged Navier-Stokes equations, coupled with two-equation k-ω turbulence closure. The sediment transport model consists of separate bed and suspended load descriptions, the latter based on a turbulent diffusion equation coupled with a reference concentration function near the sea bed boundary. Bed morphology is based on the sediment continu...
Numerical Evaluation of Fractional Vertical Soil Water Flow Equations
Ercan, Ali; Kavvas, M. Levent (2021-02-01)
Significant deviations from standard Boltzmann scaling, which corresponds to normal or Fickian diffusion, have been observed in the literature for water movement in porous media. However, as demonstrated by various researchers, the widely used conventional Richards equation cannot mimic anomalous diffusion and ignores the features of natural soils which are heterogeneous. Within this framework, governing equations of transient water flow in porous media in fractional time and multi-dimensional fractional so...
Numerical Solution of MHD Incompressible Convection Flow in Channels
Gurbuz, Merve; Tezer, Münevver (2019-1-01)
The purpose of this paper is to study numerically the influence of the magnetic field, buoyancy force and viscous dissipation on the convective flow and temperature of the fluid in a square cavity, lid-driven cavity, and lid-driven cavity with an obstacle at the center. The continuity, momentum and energy equations are coupled including buoyancy and magnetic forces, and energy equation contains Joule heating and viscous dissipation. The equations are solved in terms of stream function, vorticity and tempera...
