Rainfall triggered landslides are common threat in many regions of the world and cause loss of lives and properties. These are shallow failures (typically 3-5 m depths from the ground surface) that occur along a plane parallel to the ground surface where the groundwater level is located at significant depths below, and they are triggered after a heavy rainfall in a short time or after days of lower intensity rainfall (Huvaj et al., 2013). Considering a failure plane oriented parallel to the ground surface, ...
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...

Understanding sound propagation through variable area ducts continues to be important for controlling turbomachinery noise. In analytical treatment of the problem it is usually assumed that duct cross sections vary slowly and no mode scattering takes place. It is the purpose of this work to investigate numerically the effects of cross-sectional changes of varying degree on transmission of acoustic modes typical to turbomachinery. First, sound fields of interest through such ducts are obtained numerically by...
Numerical simulation of turbine internal cooling and conjugate heat transfer problems with Rans based turbulance models
Görgülü, İlhan; Akmandor, İbrahim Sinan; Department of Aerospace Engineering (2012)
The present study considers the numerical simulation of the different flow characteristics involved in the conjugate heat transfer analysis of an internally cooled gas turbine blade. Conjugate simulations require full coupling of convective heat transfer in fluid regions to the heat diffusion in solid regions. Therefore, accurate prediction of heat transfer quantities on both external and internal surfaces has the uppermost importance and highly connected with the performance of the employed turbulence mode...
