ABSTRACT
After a short paragraph on the ideal fluid properties, the basic equations are simplified for the case of an ideal fluid flow.
1 PRESENTATION
Although no ideal fluid exists, many real fluid flows have small viscosity and the effects of compressibility are negligible. When the boundary layer regions remain thin, the non-viscous fluid results may be applied to real fluid flow motion to a satisfactory degree of approximation. Applications include themotion of a solid through an ideal fluidwhich is applicablewith slightmodification to the motion of an aircraft through the air, of a submarine through the oceans, flow through the passages of a pump or compressor, or over the crest of a dam, and some geophysical flows.
