Inviscid flow, a simplified model in fluid mechanics, assumes the absence of viscosity, neglecting the frictional forces within the fluid. This approximation leads to the neglect of energy dissipation, allowing for a better understanding of fluid flow patterns and behavior. Inviscid flow analysis is particularly useful in understanding the fundamental characteristics of flow, such as pressure distribution and velocity profiles, and is often employed as a first approximation in aerodynamic design and analysis.
