ABSTRACT:
In a radial-axial inlet housing of rotating thermal machines, a flow divider is disposed in the turbine or compressor inlet, in front of the inlet and opposite the first turbine guide vane row or the compressor ribs. The flow divider in this case is disposed in the central lower stagnation point of the housing flow. It has a thick-headed profile with a straight median line. The rear side of the flow divider, seen in the direction of flow, is disposed perpendicularly to the rotary shaft at a distance from the first guide vane row or the ribs. There is a gap between the radially inner side of the flow divider and the housing wall, and the chord length of the flow divider decreases radially outwardly. The leading edge of the flow divider, seen in the direction of flow, is inclined like a straightened potential line relative to the housing wall.
