Abstract
An axial turbomachine including a first separation nozzle capable of separating an incoming air flow into a radially internal air flow and a flow of radially external air, called secondary flow; a second separation nozzle capable of separating the radially internal air flow into a primary flow and a tertiary flow in a tertiary flow vein radially external to the primary flow; and a heat exchanger disposed in the tertiary flow vein. The heat exchanger extends radially and axially in an upstream section of the tertiary flow vein, having a divergent longitudinal section. The tertiary flow vein includes a downstream section presenting a converging longitudinal section, following the tertiary flow.
