Cheng, X., 2020. Partial differential equations and infinite dimensional dynamic systems in marine fluid dynamics. In: Li, L. and Huang, X. (eds.), Sustainable Development in Coastal Regions: A Perspective of Environment, Economy, and Technology. Journal of Coastal Research, Special Issue No. 112, pp. 363-366. Coconut Creek (Florida), ISSN 0749-0208.In the analysis of massive hydrodynamics, we use the form of partial differential equations, which can conduct a comprehensive analysis of its dynamic system and obtain the corresponding circulation pattern of ocean currents, which can be more effective for some hydrodynamics. Analysis, in marine fluid mechanics, it includes a variety of hydrodynamic forces such as inertia viscosity, we can analyze and study them separately to get a more complete and systematic hydrodynamic research program. Fluids generally include liquids and gases, which are closely related to human daily life and social development. Fluid mechanics has typical physical properties and through practice can better deepen the understanding of the subject. Therefore, in the teaching of modern fluid mechanics, the experiment of fluid mechanics has become a typical supporting course in the course of fluid mechanics.
