4.3.1 Numerical Solution of Low Velocity Flow
For low-speed flow (flow with constant density), there are two main types of
flow in fluid mechanics, one is inviscid flow, and the other is viscous flow. For
the flow without considering viscosity, classical hydrodynamics focuses on the
incompressible and irrotational flow (potential flow) under the influence of
potential force. The solution to this kind of problem is mainly based on the
