This thesis uses the Smoothed Particle Hydrodynamics (SPH) method for simulating <br /> <br /> <br /> <br /> <br /> surface water wave propagation. The SPH method is the interpolation method <br /> <br /> <br /> <br /> <br /> used in the particle system to evaluate the value of physical quantities that become <br /> <br /> <br /> <br /> <br /> identity of each particle. In its implementation, the fluid is represented as a set of <br /> <br /> <br /> <br /> <br /> particle and each particle has physical quantities, such as mass, position, velocity, <br /> <br /> <br /> <br /> <br /> density, and pressure. Interpolation using the SPH method is done by distributing <br /> <br /> <br /> <br /> <br /> the value of physical quantities to all neighbor particles from each evaluated particle. <br /> <br /> <br /> <br /> <br /> The model and simulation are made using fluid particles in a rectangular tank. <br /> <br /> <br /> <br /> <br /> Water waves are generated by flap type wavemaker and measurements are taken for <br /> <br /> <br /> <br /> <br /> some variables. <br /> <br /> <br /> <br /> <br /> The purposes of the research in this thesis are to study the characteristics of the <br /> <br /> <br /> <br /> <br /> flap type wavemaker and the behaviors of the water waves by governing different <br /> <br /> <br /> <br /> <br /> parameters. The studies are done by calculating the wave elevation for each time <br /> <br /> <br /> <br /> <br /> step. Wave elevation profiles, wave amplitude, wave period, and wavelength were <br /> <br /> <br /> <br /> <br /> studied for some cases depending on changes in variable water depth, flap period, <br /> <br /> <br /> <br /> <br /> flap stroke amplitude, and other variables. In order to examine the accuracy of the <br /> <br /> <br /> <br /> <br /> model, the numerical simulation results of the SPH method were validated using <br /> <br /> <br /> <br /> <br /> wavemaker theory and linear wave model and compared to the analytical solutions. <br /> <br /> <br /> <br /> <br /> It has been observed that the SPH method are in good agreement with wavemaker <br /> <br /> <br /> <br /> <br /> theory and linear wave model. The numerical simulation results of the SPH method <br /> <br /> <br /> <br /> <br /> agree with the analytical solutions.
