Inviscid flow refers to fluid motion that occurs without viscosity, meaning that the fluid has no internal resistance to shear stress. This concept is crucial in the study of aerodynamics and fluid dynamics because it simplifies the analysis of fluid behavior around objects, allowing engineers to model airflow without accounting for viscous effects, which can complicate calculations and simulations. Understanding inviscid flow helps in predicting how air interacts with wings and other surfaces, which is vital for designing efficient aerodynamic shapes.
