Pressure Pulsation of Scroll Compressor
Advanced Energy Systems, 1997Abstract Pressure pulsation in the scroll compressor was analyzed with three dimensional FLIC (flow in cell) method which was a kind of finite volume method. In advance of analyses, the grid generation method for numerical analysis was established in the scroll compression chamber.

Pressure pulsations on an obstacle in a jet
Fluid Dynamics, 1980At the present time, much attention is devoted to auto-oscillations that arise from the interaction between a supersonic underexpanded jet and an obstacle that it encounters at right angles [1, 2]. There are far fewer data on the pressure pulsations on an obstacle in the absence of auto-oscillations [3–6].

The effect of pressure pulsations on the Fahraeus-Lindqvist effect
Microvascular Research, 1978Abstract The effect of superposition of pressure pulses on the steady flow of blood through narrow tubes with diameters in the Fahraeus-Lindqvist range was studied experimentally to determine whether pulsations modify the diameter-dependent viscosity reduction of blood in these rigid tubes.

Microcirculatory response to periodic pulsations in capillary pressure
Microvascular Research, 1982Abstract A mathematical analysis of time-dependent convection and diffusion in the microcirculation is presented in order to ascertain the effect on capillary-tissue fluid exchange of cardiac pulsatility and the rhythmic contractions of arterioles and precapillary sphincters.

Pressure pulsations in the piping of reciprocating pumps
Chemical Engineering & Technology, 1987AbstractPressure pulsations in hydraulic systems, generated by reciprocating pumps, can cause serious problems with regard to plant safety and reliability. In particular, fatigue problems arise in high‐pressure piping systems. The available knowledge is not sufficient for an accurate computation of pressure peaks in the piping of reciprocating pumps. A

Research on a new pressure pulsator
Physics of FluidsPulsators are widely used to study the dynamic characteristics of liquid flow components. However, it is difficult to adapt the existing actuators to the excitation requirements under high pressures, low temperatures, and toxic media. This study describes the design of a novel pressure pulsation device and presents the results of simulations and ...

Analysis of Pressure Pulsation in Hypercompressor Pipeline
Volume 3: Fluid-Structure Interaction; High Pressure Technology, 2022Abstract The discharge pressure of hypercompressors in Low Density Polyethylene (LDPE) Plants reaches 350 MPa or higher, its safety and reliability requirements are extremely high. The pipeline vibration is the most important factor that involves the safety of the compressor.

Relationship between arterial pulsations and intraocular pressure
Experimental Eye Research, 1983A model of the eye is proposed in order to find a relationship between small changes in volume and the intraocular pressure in terms of the physical parameters of the globe. The results show that pulsations in pressure due to small variations in volume are directly proportional to the average intraocular pressure and inversely proportional to the ...
