The runup of long waves on the sloping planes is described by the analytical solutions of the long wave equations with special initial conditions, proper approximations and boundary conditions. These studies are also compared with experimental data (Yeh et al. (1996); Lin et al. (1999); Yalciner et al. (2003)). Similarly the numerical methods solving governing equations with proper boundary conditions are also developed and compared with either analytical or experimental or field data for long wave propagation and runup. In this study particularly, the experimental set up is applied in the numerical model with the same wave and boundary conditions. The computed shape and amplitude evolution of the wave at the complex topography are compared with the existing experimental results. The performance of the numerical method is also discussed.

Nonlinear mixing length model for prediction of secondary currents in uniform channel flows Aydın, İsmail (American Society of Civil Engineers (ASCE), 2009-01-29) A nonlinear turbulence model for numerical solution of uniform channel flow is presented. Turbulent stresses are evaluated from a nonlinear mixing length model that relates turbulent stresses to quadratic products of the mean rate of strain and the mean vorticity. The definition of the mixing length, based on a three-dimensional integral measure of boundary proximity, eliminates the need for solution of additional transport equations for the turbulence quantities. Experimental data from the literature for c...
Free surface wave interaction with an oscillating cylinder Bozkaya, Canan (2014-01-01) The numerical solution of the special integral form of two-dimensional continuity and unsteady Navier Stokes equations is used to investigate vortex states of a horizontal cylinder undergoing forced oscillations in free surface water wave. This study aims to examine the consequence of degree of submergence of the cylinder beneath free surface at Froude number 0.4. Calculations are carried out for a single set of oscillation parameters at a Reynolds number of R = 200. Two new locked-on states of vortex forma...
Nonlinear evolution and runup–rundown of long waves over a sloping beach Kanoğlu, Utku (Cambridge University Press (CUP), 2004-8-25) The initial value problem of the nonlinear evolution, shoreline motion and flow velocities of long waves climbing sloping beaches is solved analytically for different initial waveforms. A major difficulty in earlier work utilizing hodograph-type transformation when solving either boundary value or initial value problems has been the specification of equivalent boundary or initial condition in the transformed space. Here, in solving the initial value problem, the transformation is linearized in space at t = ...
FORCED HARMONIC RESPONSE ANALYSIS OF NONLINEAR STRUCTURES USING DESCRIBING FUNCTIONS TANRIKULU, O; KURAN, B; Özgüven, Hasan Nevzat; IMREGUN, M (1993-07-01) The dynamic response of multiple-degree-of-freedom nonlinear structures is usually determined by numerical integration of the equations of motion, an approach which is computationally very expensive for steady-state response analysis of large structures. In this paper, an alternative semianalytical quasilinear method based on the describing function formulation is proposed for the harmonic response analysis of structures with symmetrical nonlinearities. The equations of motion are converted to a set of nonl...
Numerical simulation of non-reacting turbulent flows over a constant temperature solid surface in regression Karaeren, Cenker; Albayrak, Kahraman; Department of Mechanical Engineering (2007) In this study, an attempt is made to obtain convergent and stable solutions of the K-E turbulence model equations for non-reacting turbulent flows over an isothermal solid surface in regression. A physics based mathematical model is used to describe the flow and temperature field over the moving surface. The flow is assumed to be two-dimensional, unsteady, incompressible with boundary layer approximations. Parabolized form of the standard K-E equations is adopted to simulate turbulence in the flow. Regressi...
