Investigation of Unsteady Pressure Pulsations of Reactor Coolant Pump Passage under Flow Coast-down

Machines, 2023
In order to obtain the pressure pulsations of a reactor coolant pump during flow coast-down conditions, the time-domain characteristics of the flow passage under different times of flow coast-down were calculated by numerical calculation.

Retinal Vein Pulsation is in Phase with Intracranial Pressure and not Intraocular Pressure

Investigative Opthalmology & Visual Science, 2012
As efforts to noninvasively measure intracranial pressure (ICP) increase, we thought it important to investigate the timing of retinal venous pulsation in relation to the intraocular and intracranial pressure pulses.Neurosurgical patients undergoing continuous direct ICP monitoring had video recordings of ICP, IOP, and retinal venous pulsation ...

Pressure Analysis in the Draft Tube of a Pump-Turbine under Steady and Transient Conditions

Energies, 2021
Pumped-storage power stations play a regulatory role in the power grid through frequent transition processes. The pressure pulsation in the draft tube of the pump-turbine under transient processes is important for safe operation, which is more intense ...
