摘　　要：针对船舶与海洋工程流体力学的特点,分析欧拉和拉格朗日方法的不同假设及两种方法解决不同问题的优缺点,通过数学分析和数值建模来解决船舶与海洋工程具体工程问题,利用欧拉方法解决水下蛙人运载器水下航行水动力性能分析问题,利用拉格朗日方法解决LNG船舶液舱晃荡问题、集装箱船艏部入水冲击问题,引导学生深刻理解流体力学的本质,学会采用不同方法解决不同问题,为船舶流体力学的教学探索一种全新模式。According to the teaching characteristics of the introduction course of ship and ocean engineering,combined with the teaching concept of interdisciplinary integration of new engineering education,an innovative teaching method based on fluid mechanics is proposed.This method takes scientific basic theory as the starting point,the industrial technology as the foothold to inspire students to deeply think about new ideas and technologies based on the national development strategies in the field of ship and ocean engineering.Based on fluid mechanics,Euler and Lagrange methods are presented to solve specific engineering problems of ship and ocean engineering.Euler method is used to solve the underwater navigation hydrodynamic performance analysis problem of Diver Propulsion Vehicle(DPV),and the Lagrangian method is used to solve the sloshing problem in the liquid tank of LNG ships and the water entry impact problem of the bow of container ships,guiding students to put forward innovative thinking and practical verification in combination with the study of this major,and exploring a new teaching mode for introduction of fluid mechanics.
