Identify whether a radial, mixed, or axial flow machine is best suited for a specific application based on its operating point.
Turbomachinery design is central to modern energy and process industries: Industrial Applications
Determine the highest possible efficiency for a given set of flow conditions.
While Balje focuses heavily on high-speed compressible flow (centrifugal compressors and turbines), the principles apply to incompressible fluids like water in hydraulic turbines. Industrial Applications
