Ideal Fluid

An ideal fluid is a theoretical concept in physics representing a perfect fluid that is inviscid (has no viscosity), incompressible, and flows smoothly without turbulence or internal friction. In reality, all fluids have some viscosity and compressibility, but the ideal fluid model simplifies analysis by assuming these factors are zero. This concept helps scientists understand fluid behavior in situations like airflow over wings or water flowing in pipes, providing a foundation for more complex real-world studies. It's a useful approximation for analyzing fluid dynamics under idealized conditions.
