bellmouth
Widening inlet shape
A bellmouth is a flared opening shaped like the bell of a trumpet, designed to smooth the flow of air, water, or other fluids.
The term appears in engineering contexts—pipe fittings, spillways, air intakes—where a gradual widening reduces turbulence: The reservoir drains through a bellmouth spillway.
As a verb, to bellmouth is to create such a flare.
