Abstract
A system for improving fuel-air mixing inside an injection system of a turbomachine combustion chamber. An air intake ring has an annular deflection wall, or venturi, having an internal profile provided with a discontinuity inducing an increase in the radius (φ) of the internal profile downstream of the discontinuity. A method of atomizing fuel includes separating fuel trickling over the internal profile of the annular deflection wall from the internal profile at the level of the discontinuity so as to form droplets within a flow of air coming from an upstream air circulation space of the air intake ring.

An air intake ring for an injection system of a combustion chamber of a turbomachine, having an axis of revolution, and comprising an annular separation wall that divides the air intake ring into an upstream air circulation space and a downstream air circulation space, and that extends radially inwards into an annular deflection wall having an internal profile with a convergent-divergent shape, wherein the internal profile of the annular deflection wall has a discontinuity that induces an increase in the radius of the internal profile downstream of said discontinuity.
