In this report, we investigate the physical and dynamical properties of model fluids whose constituent particles have their softness varied in a systematic manner. Molecular dynamics (MD) computer simulation is applied to inverse power or soft-sphere fluids, in which the particles interact through ...
Although the bulk modulus of aerated hydraulic fluids at different temperatures have been measured experimentally, theoretical calculation formulas have not been derived. Therefore, a dynamic model of an aerated hydraulic fluid is introduced herein. In the dynamic model, the lumped parameter method is ...
the case pressure is set to 0.1 MPa. In this study, the case pressure is set as the reference liquid pressure. ISO VG 32 oil is utilized as the fluid medium. The geometry of the CFD model and properties of the hydraulic oil are presented in Table1. The physical properties of the hydra...
Agitation (Mechanical) refers to the process of using fixture movement to create currents near surfaces in fluids, disrupting stagnant boundary layers. This can be achieved through low or high pressure fluid flow, bubbling gases, or hydrosonic pressure waves in a fluid tank. ...
The dies should part along a single, flat plane if at all possible. If not, the parting plane should follow the contour of the part. The parting surface should be a plane through the center of the forging and not near an upper or lower edge. ...
The amount of gas between the seal faces of an idealized seal depends on the fluid properties, sealing pressure and sealing temperature. For example, high vapor pressure fluids like propane will have a large percentage of the seal face width operating with gas between the faces. The hydrocarbon...
With the development of gear transmission towards high load carrying capacity, high speed, and high precision, etc., the effects of EHL characteristics of the oil film between the teeth surfaces on gear drive have attracted widespread attention, and the non-Newtonian characteristics of fluids, therm...
fluids, which is an improvement of traditional theories. The latter simplifies the internal body dynamics and highlights hydrodynamics, which treats fish swimming as a FSI problem. In view of the advantages and disadvantages of dynamic model and CFD method (shown in Figure2), some researchers have...
