The complex nature of the dependence of the voltage pulsation
coefficient on the parameters of the mode excludes the possibility of obtaining it in an analytical form.
Recently, various analytic and simulative methods have been extensively studied on distribution of flow field and working pulsation
. Particularly, the CFD simulation is generally utilized in many fluid field and hydraulic researches.
(i) confirmation of the dependence of IOP on the blood pulsation
Analysis of Fluid Pressure Pulsation
. Vibration analysis of pressure pulsation
enhances both hydraulic and dynamic performance and assures safety and reliability of the pumping station.
Generally, it is believed that the higher the harmonic order, the lower the pressure pulsation
energy and the lower amplitudes correspondingly.
Oscillations are created by vibration or pulsation
Research of a level of pressure fluctuations reducing in the normal pump operation mode has shown that the regular damper reduces the pressure pulsation
to 1.3 ...
The wide range applications of the PMBLDC motor drives from ranging ships propulsion to robotics is another motivation of many researchers to investigate new methodologies for reducing the torque pulsation
and speed ripple.
Also, production of pulsation
in flow was considered by using synthetic jets .
The expansions will enhance current capabilities to test products in a real world environment, factoring in multiple variables at one time such as temperature, humidity, vibration, pulsation
and flow as well as various contaminants.
Furthermore, the changes of the mean density of the gaining star as a result of accretion of matter can affect the pulsation
periods and pulsation
properties of oEA stars.
