Relationship between Axial Width and Flow Characteristics of Pump Chamber in Double Volute Centrifugal Pump

Xibei Gongye Daxue Xuebao, 2020
The axial width of pump chamber has a great influence on the flow characteristics of the pump chamber in the centrifugal pump. A single-stage single-suction double volute centrifugal pump with a semi-open impeller was selected as the object.

Radial velocity follow-up of GJ1132 with HARPS [PDF]

Astronomy & Astrophysics, 2018
The source GJ1132 is a nearby red dwarf known to host a transiting Earth-size planet. After its initial detection, we pursued an intense follow-up with the HARPS velocimeter. We now confirm the detection of GJ1132b with radial velocities alone.

Characterization of the radial velocity signal induced by rotation in late-type dwarfs [PDF]

, 2017
We investigate the activity induced signals related to rotation in late type stars (FGKM). We analyse the Ca II H&K, the H alpha and the radial velocity time-series of 55 stars using the spectra from the HARPS public database and the light-curves ...

The Open Cluster NGC 7789: I. Radial Velocities for Giant Stars

, 1998
A total of 597 radial-velocity observations for 112 stars in the ~1.6 Gyr old open cluster NGC 7789 have been obtained since 1979 with the radial velocity spectrometer at the Dominion Astrophysical Observatory. The mean cluster radial velocity is -54.9 +/
