METHOD AND DEVICE FOR NUMERICAL SIMULATION OF SHIP SELF-PROPULSION POINT, AND COMPUTER APPARATUS

摘要

A method and device for the numerical simulation of a ship self-propulsion point, and a computer apparatus. By detecting whether parameters of a flow field satisfy a preset stable state condition, a compelling force in relatively stable parameters of the flow field can be obtained in advance; the obtained current compelling force is compared with a target compelling force; if the magnitude relationship between the current compelling force and the target compelling force does not satisfy a preset magnitude relationship, a propeller of a ship is corrected according to a preset correction coefficient; the current compelling force obtained after the correction is compared with the target compelling force; by means of multiple times of corrections and by setting a correction coefficient for a next time to be not less than that for a last time, the current compelling force and the target compelling force can be quickly made to satisfy the preset magnitude relationship, thereby quickly and precisely selecting a ship self-propulsion point. The calculation complexity for numerical simulation calculation is reduced; in addition, excessive manual participation is avoided in the calculation process, and the calculation efficiency is improved.
