Revised FORTRAN program for calculating velocities and streamlines on the hub-shroud midchannel stream surface of an axial-, radial-, or mixed-flow turbomachine or annular duct. 2: Programmer's manual [PDF]
A FORTRAN IV computer program has been developed that obtains a detailed subsonic or shock free transonic flow solution on the hub-shroud midchannel stream surface of a turbomachine.

Impeller-Induced Rotor-Dynamic Forces [PDF]
, 1989 The flow through and around the rotor of a turbomachine exerts a force on the rotor and, hence, rotor shaft and bearing system. In some circumstances this force may lead to excitation of shaft whirl in the direction of impeller rotation.

Battery Energy, Volume 4, Issue 5, September 2025.A novel electrolyte for all‐iron redox flow batteries has been proposed with NaHSO3 as a key component. Even in small amounts, it significantly increases the plating/stripping processes occurring in the negative half‐cell (limiting step). Thanks to the formation of a FeHSO3+ intermediate, which acts as a very effective catalyst for the metallic iron ...

Energy Science &Engineering, Volume 13, Issue 9, Page 4356-4370, September 2025.ABSTRACT This study establishes a full‐flow passage numerical model of an LNG submerged pump equipped with two‐stage splitter blades through three‐dimensional modeling. Numerical simulations validated by liquid nitrogen experiments demonstrate that at 1.4 times the design flow rate, the peak efficiency reaches 60.6%, with a maximum head of 194.93 m ...
