Viscosity is an important fluid property when analyzing liquid behavior and fluid motion near solid boundaries. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. The shear resistance in a fluid is caused by inter-molecular friction e...

10.26.3.1.1(ii)Kinematic viscosity In many situations, we are concerned with the ratio of the viscous forceµto the inertial force; the latter characterized by the fluid density,ρ. This ratio is called thekinematic viscosityand is denoted byη=µ/ρ. ...
I am simulating the mass and heat transfer of hydrogen stored in La-Ni5 alloy. Some references say they treated hydrogen kinematic viscosity as a constant, but did not give the value. Does anyone knows what is the value of hydrogen kinematic viscosity in a reacting tank with temperature ran...
G as in an average speed gradient caused by the turbulent kinetic energy produced; a is the turbulent kinetic energy; b dissipation rate; u for kinematic viscosity of the liquid,,, =0.09[13]. And are the corresponding to the turbulent kinetic energy dissipation rate of the Prandtl number. ...
Where θc refers to the contact angle of GDL, x = Lgdl + Lcl, σ is the surface tension, Kc denotes the GDL permeability, and vl is the liquid water Kinematic viscosity. The equilibrium water content in formulas (4) and (5) is given as below[41]: (7)λeq=0.043+17.81a-39.85a2+...
through the fluid by an external and controlled force such as a spindle driven by a motor. In either case, the resistance to flow (or shear) as a function of the input force is measured, which reflects the internal resistance of the sample to the applied force, or its dynamic viscosity....
In recent years, iron-based ionic liquids (e.g. BmimFeCl4, Fe-IL) have been widely used in the catalytic oxidation removal of hydrogen sulfide owing to their excellent redox reversibility and stability. Nevertheless, the high viscosity a... W Bai,J Chen,F Liu,... - 《Physical Chemistry...
Effects of the kinematic viscosity and surface tension on the bubble take-off period in a catalase–hydrogen peroxide system The effect of kinematic viscosity and surface tension of the solution was investigated by adding calatase, glucose oxidase, or glucose on the bubble moveme... S Sasaki,Y...
