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.

Oljekrets behövs i en jetmotor i syfte att smörja och kyla dess inre mekaniska komponenter. Oljan som pumpas från reservoaren passerar igenom värmeväxlare. Oljan injiceras sedan på kullagren som kräver kontinuerlig smörjning och kylning innan den når sitt slutförlopp i botten av tråget där den filtreras och dirigeras tillbaka till reservoaren ...
