Guide vanes for fully reversible turbomachinery

A fully reversible turbomachinery comprising:

• an impeller configured to rotate in a first rotational direction, where the impeller rotating in the first rotational direction causes gas to flow in a first flow direction through the fully reversible turbomachinery, and a second rotational direction, where the impeller rotating in the second rotational direction causes the gas to flow in a second flow direction through the fully reversible turbomachinery, the second rotational direction being opposite of that of the first rotational direction, the first flow direction being opposite of the second flow direction;
• and
• one or more guide vanes disposed in proximity to the impeller, each guide vane including:
• an asymmetrical first edge configured to convert a rotational flow exiting the impeller into a downstream axial flow;
• a symmetrical second edge opposite of the asymmetrical first edge, wherein each guide vane is disposed in proximity to the impeller such that the asymmetrical first edge is disposed more proximate to the impeller than the symmetrical second edge;
• an upper planar surface extending from the asymmetrical first edge to the symmetrical second edge;
• and
• a lower planar surface opposite the upper planar surface, the lower planar surface extending from the asymmetrical first edge to the symmetrical second edge.

A guide vane for a fully reversible turbomachinery, the guide vane comprising:

• a profiled first edge;
• a symmetrical second edge opposite the profiled first edge;
• an upper planar surface spanning from the profiled first edge to the symmetrical second edge;
• and
• a lower planar surface opposite the upper planar surface, the lower planar surface spanning from the profiled first edge to the symmetrical second edge, wherein the profiled first edge is configured to convert rotational flow exiting an impeller of the fully reversible turbomachinery into an axial flow.
