A CFD parametric study of geometrical variations on the pressure pulsations and performance characteristics of a centrifugal pump. [PDF]
Pressure pulsations may be troublesome during the operation and performance of centrifugal pumps. Such pressure pulsations have traditionally been investigated experimentally but numerical analysis techniques allow these effects to be explored. The multi-

Air pressure pulsation solid state fermentation of feruloyl esterase by Aspergillus niger
Air pressure pulsation solid state fermentation (APP-SSF) was applied to produce feruloyl esterase (FAE) by Aspergillus niger. With the optimization of some variables by orthogonal design, the optimal condition obtained was 0.2 MPa (gauge pressure) of ...

Numerical Simulation of Pressure Pulsations in Francis Turbines
For more than 150 years, hydraulic power plants have been strongly contributing to energy generation. At present, with the expanding participation of other non-storable renewable energy sources in the electrical market composition, water turbines can importantly contribute to the electrical grid stability and to energy storage.
