👉 In fluid dynamics, a type of flow that is not characterized by any vortices or eddies. Non-vortical flows are characterized by an absence of vortex formation, and they can be classified into two main categories based on their behavior:
1.
Non-Viscous Flow
: A non-viscous flow is one where the Reynolds number (a measure of fluid velocity) is less than or equal to 2000. In this type of flow, there are
