(9). This study adopts a commonly used boundary treatment method, the non-slip rigid wall boundary proposed by Takeda et al. (1994) and Morris et al. (1997), because of its simplicity and effectiveness (Bui and Fuka- gawa, 2013; Zhang et al., 2016, 2019b; Peng et al., 2019). ...
A no-slip condition was assumed between the drilling fluid and the boundary wall which in this case is a wellbore. Particles (cuttings) are considered spherical in shape with a density of 2.80 kg/m3 and an inlet cutting concentration (volume fraction) of 0.08. It is assumed that there is ...
The inset in Fig. 2(a) presents a serrated (jerky) curve for the bare sample under high load, which is the result of stick-slip motion associated the high fric- tion surfaces. In contrast, the curve for TFMG is smooth. Table 1 lists the peak forces associated with the insertion ...

No-slip boundary condition is applied at the enclosure or cavity walls and the system is hence established on single-phase model. The porosity is uniform, and nanoparticles are spherical shaped. Thermal conductivity of nanofluid is identical to the thermal conductivity of the porous zone in the ca...
Due to the no-slip boundary condition, the velocity is quite low, close to the bottom wall. The upper unyielded portion did not touch any wall. The velocities are non-zero in this chamber portion because of the lid motion. Lid motion allows the fluids to move in the upper part of the...
Concerning the tectonic environment, earthquakes in Indonesia are dominated by either the strike–slip or subduction earthquake mechanism. In particular, Bandung (which is the main investigated region in this study) is surrounded by several active faults. This was the main motivation in selecting the...
Non-slip vs slip-resistant shoes: What is the difference? The two terms non-slip and slip-resistant are similar and can be used interchangeably. They both imply a type of footwear that can protect the wearers from injuries when walking on slippery surfaces. ...
