Experimental research of power loads on surface structure based on 3D model of wave processes

Abstract

The article is devoted to the research of the influence of wave processes on surface structures using mathematical model of wave processes. The mathematical model is based on the system of Navier-Stokes equations, which includes three equations of motion in areas with dynamically changing geometry of the computational domain. Pressure-correction method is used is used to approximate the hydrodynamic model. The difference schemes describing the mathematical model of the wave propagation towards the shore are constructed on the basis of the integro-interpolation method using the scheme with weights. Adaptive alternating-triangular iterative method is used to solve the system of grid equations. The practical significance of numerical algorithms and complex of programs consists in the possibility of their application in investigation of hydrophysical processes in coastal water systems, as well as for construction the velocity and pressure fields of the aquatic environment. It also allows you to evaluate of the hydrodynamic effect on coastal protective structures and riparian constructions in the presence of surface waves.The article is devoted to the research of the influence of wave processes on surface structures using mathematical model of wave processes.
