introduction：wunianxing buke yasuo liuti donglixue Inviscid incompressible fluid dynamics classical hydrodynamics Fluid dynamics is a branch of fluid dynamics that deals with the flow of inviscid incompressible fluids around objects and in tubes，Also known as classical fluid dynamics。The task of this branch of the discipline is to find the velocity in a flow field、Pressure distribution and force on objects。It ignores the viscosity and compressibility of real fluids，Surface tension is not taken into account，This greatly simplifies complex fluid dynamics
