Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles
Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.

From the reviews, a new concept of a low‐speed centrifugal pump (LSCP) driven by a vertical ultra‐low‐head hydro turbine (VULHT) was designed and tested on simulation and physical setup. It was performed with a 1.8 m delivery head, concluding as inefficient. For ultra‐low‐head conditions, different than centrifugal action is recommended.
