In this work, an unsteady incompressible viscous magnetic-hydrodynamic squeezing of flow fluid is investigated. By the help similar variables and appropriate transformations which play important role to convert non-linear partial differential system into ordinary equation. Also, reduced boundary value problem resolved analytically by employing a derivatives series algorithm (DSA). The key for c...

A numerical model replicating the stick-slip contact of two elastically similar materials is presented in this paper. Based on Coulomb's law described partial-slip theory Ciavarella, adopts a complementary condition that facilitates design novel algorithm to separate stick and slip regions. Via comparison between simulation results analytical solutions, developed validated applied study role pl...

We study the hydrodynamic viscous electronic transport in a two-dimensional sample separated into two semi-infinite planes by one-dimensional infinite barrier. The are electrically connected via finite-size slit calculate current through assuming finite voltage drop between and neglecting disorder-induced Ohmic resistance, so dissipation resistance purely viscosity induced. find that only solut...

The combined effects of magnetic field, Navier slip and convective heating on the entropy generation in a flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel plates under a constant pressure gradient have been examined. Both the lower and upper plates of the channel are subjected to asymmetric convective heat exchange with the ambient fluid. T...

The inconsistencies regarding the fundamental correlation between Gd content and slip (twinning) activities of Mg alloys appeal further investigations. However, traditional dislocations analysis by TEM is time-consuming, that SEM/EBSD cannot recognize partial modes. These urge a more efficient comprehensive approach to easily distinguish all potential modes occurred concurrently in alloy matrix...

BACKGROUND Small nasotracheal tubes (NTTs) and intranasal compression of the NTT in the nasal cavity may contribute to increasing airway resistance. Since the effects of size, shape, and partial compression of the NTT on airway resistance have not been investigated, values of airway resistance with partial compression of preformed NTTs of various sizes were determined. METHODS To determine th...

The effects of thermal and velocity slip on Newtonian fluid steady boundary layer stagnation-point flow heat transfer through a porous shrinking sheet with suction effect are investigated in the present research. By using similarity transformation, partial differential equation (PDE) is converted to an ordinary (ODE) solved shooting technique get numerical results. characteristics for various v...

in this paper the factor of safety (fs) and critical line-segments slip surface obtained by the alternating variable local gradient (avlg) optimization method was presented as a new topic in 2d. results revealed that the percentage of reduction in the fs obtained by switching from a circular shape to line segments was higher with the avlg method than other methods. the 2d-avlg optimization meth...

the majority of existing tractors in iran are not equipped with any tools to measure and display slip and ground speed. this is mainly due to the lack of national standards for measuring tools and instruments of tractors. in current research, an interchangeable system for two wheel drive tractors has been designed. furthermore, it has been assessed after construction. to measure actual and theo...

Experiments were conducted to discern the turbulence augmentation achieved over a bristled shark skin model embedded inside a turbulent boundary layer. It is hypothesized that shark scales are passively bristled by the flow in regions where incipient separation is present. The formation of embedded vortices within the model leads to the presence of partial slip velocities adjacent to the main b...
