dc.description.abstractThis thesis investigates violent non linear turbulent flows and their structural interactions in two and three dimensions using a smoothed particle hydrodynamics (SPH) model accelerated using central processing units (CPUs) with additional neural stick. The technique of smoothed particle hydrodynamics (SPH), a mesh free particle method is getting main stream starting late to model non linear problems of coastal engineering. SPH consists of numerous particles in the predefined domain without inter connectivity. The main limitation of SPH that resists the method s potential is their lack of providing stability and accuracy to the numerical technique. The accuracy of the standard SPH technique has been improved in this thesis by formulating a new inverse logarithmic kernel function. This new kernel function has been derived based on the properties of kernel functions. Our new proposed kernel showed some improvement over the existing kernel by showing very less error approximation of 0.035h2 in second order momentum approximations. newlineThe efficiency of the new kernel function was tested in two different cases. The 2D shock wave propagation has been simulated using MATLAB to investigate the capability of handling the mathematical discontinuities using our new kernel function. Later, the 3D dam - break phenomena for two different scenarios such as experimental and Mullaiperiyar reservoir have been carried. The 3D dam break experimental validation showed a closer agreement between the experimental newline
