Моделирование процесса обледенения корпуса рыболовецкого судна на поверхности воды с учетом влияния волнения

Abstract

Studying the icing of ships is an urgent task. The paper considers the problem of modeling the flow of a model vessel with a gas-droplet flow and the occurrence of the icing process. Initially, the simulation was performed using the interDyMFoam solver, taking into account the assignment of the Stokes wave of the first kind to determine the position of the droplets. Further modeling was carried out using the iceFoam solver, which is based on the Euler-Lagrangian method for describing the gas-droplet flow. The considered model of a fishing vessel had a scale of 1:10. The position of the droplets was set at the entrance to the calculated rectangular domain. The estimated grid had from 1.5 to 10 million. cells. With the help of calculations, the trajectories of droplet movement around the hull of the vessel, the distribution of the air velocity field, the position of the water film and the thickness of ice on the deck surface were obtained. The mass of the overgrown ice was estimated. The simulation was performed on the computing cluster of the ISP RAS. One typical calculation was run on 48-96 computing cores and lasted no more than three days.
