Conical Wall

A conical wall is a precision-engineered component with a tapered geometry, typically forming part of a diverging section in fluid handling systems. It functions as a transition element that gradually increases the cross-sectional area along the flow direction, converting kinetic energy to pressure energy through controlled expansion. This component is critical for minimizing turbulence, preventing flow separation, and ensuring efficient energy recovery in applications ranging from industrial pipelines to ventilation systems.

The conical wall operates on the principle of gradual area expansion, where the tapered geometry reduces fluid velocity according to the continuity equation (A1V1 = A2V2) while increasing static pressure through Bernoulli's principle. This controlled deceleration minimizes energy losses from sudden expansion, reduces shear stress, and maintains laminar or transitional flow regimes to prevent separation and recirculation zones.
