Examples of the processed images are shown in Fig. 5, where R is the viscosity ratio as defined in Eq. (2). Fig. 4 a Single-color image and b binary image at R=78.5 Full size image Fig. 5 Fluid displacement in a 45-degree fractured medium at Q = 35.88 ml/min, with a R = ...
whereas stick-slip bubbles prevail at highϕandVair. The theoretical model for the phase boundary is superimposed on the images (black line), including the effect of a ±10% variation in the friction coefficientμ(
Friction-related WSS, tangentially affecting the surface of mechanosensitive endothelial cells (ECs) lining the inner wall of blood vessels18, is thought to play a key role in directing remodelling19,20. Local blood disturbance and multidirectional flow lead to variations in the WSS vector21that can...

Serous fluids, including pleural, pericardial, and peritoneal fluids, normally exist in very small quantities and serve as lubricant between the membranes of an organ and the sac in which it is housed to reduce friction.16 Pleural fluid is found in the space between the lungs and the pleural ...
Additives are necessary to control viscosity of the fluid, sedimentation of particles and interparticle friction, in addition to prevent thickening of the fluid after several cycles of use [25]. Thixotropic agents form a network of particles which creates a weak structure at low shear rates and ...
This property, about which more will be said later, is a measure of the friction that arises when adjacent layers of fluid slip over one another. It follows that the shear stresses are everywhere zero in a fluid at rest and in equilibrium, and from this it follows that the pressure (...
Turbulence, In fluid mechanics, a flow condition (see turbulent flow) in which local speed and pressure change unpredictably as an average flow is maintained. Common examples are wind and water swirling around obstructions, or fast flow (Reynolds number
A friction pad to be used in conjunction with a cartridge in a caulking (or any cartridge type) dispenser. The invention contemplates using the friction pad in conjunction with an existing caulking di
A fluid actuated friction damper having telescopically movable inner and outer bodies, the outer body having an elongated, continuous friction surface. The inner body includes a first set of friction shoes engageable with the continuous friction surface, a fluid pressure responsive device for exerting...
