Large-Eddy Simulation of Unsteady Flow in a Mixed-Flow Pump
International Journal of Rotating Machinery, 2003 This article describes the large-eddy simulation (LES) of the internal flows of a high–specific-speed, mixed-flow pump at low flow-rate ratios over which measured head-flow characteristics exhibit weak instability. In order to deal with a moving boundary

Experimental Study on Cavitation in Mixed-Flow Pump Impellers
Transactions of the Japan Society of Mechanical Engineers, 1963 Several mixed-flow pump impellers were tested in a test pump for the purpose of studying the effects of the number of vanes and the inlet edge shape on their performance and cavitation characteristics. The shockless entry flow rates were obtained from the incipient cavitation conditions and inlet flow deviation angles were found, their degree varying ...

Performance Evaluation and Dimensional Analysis of Multistage Helicoaxial Pump for Two-Phase Flow
International Journal of Turbomachinery, Propulsion and Power, 2019 A four stage helicoaxial pump was tested under varying operating conditions. A range of inlet pressures, rotational speeds (3000, 3600 rpm), and gas void fractures (GVFs) were considered for two fluid viscosities.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

CFD Analysis of Cavitation Phenomena in Mixed-Flow Pump [PDF]
International Journal of Fluid Machinery and Systems, 2012 This paper deals with the CFD analysis of cavitating flow in the mixed-flow pump with the specific speed of 1.64 which suffers from a high level of noise and vibrations close to the optimal flow coefficient. The ANSYS CFX package has been used to solve URANS equations together with the Rayleigh-Plesset model and the SST-SAS turbulence model has been ...
