Funnel Flow Comparison: Constricted vs. Narrow-Channel Designs #2155823 (License: Personal Use)

The left diagram depicts a funnel with a rectangular constriction zone, where the blue flow path widens slightly before narrowing, potentially causing turbulence or pooling. The right diagram shows a streamlined funnel with a continuous narrow vertical channel, promoting laminar flow and minimizing resistance. Both include a red centerline indicating the central axis of symmetry.

Used in engineering, physics, or industrial design educational content to explain fluid dynamics, hopper design, or material handling systems; targets students, designers, or technical professionals seeking to optimize flow efficiency.
