Shear viscosity coefficient of liquid lanthanides
Abstract
Present paper deals with the computation of shear viscosity coefficient (η) of liquid lanthanides. The effective pair potential v(r) is calculated through our newly constructed model potential. The Pair distribution function g(r) is calculated from PYHS reference system. To see the influence of local field correction function, Hartree (H), Tailor (T) and Sarkar et al (S) local field correction function are used. Present results are compared with available experimental as well as theoretical data. Lastly, we found that our newly constructed model potential successfully explains the shear viscosity coefficient (η) of liquid lanthanides.

Temperature dependence of the yield shear resultant and the plastic viscosity coefficient of erythrocyte membrane: implications about molecular events during membrane failure
Structural failure of the erythrocyte membrane in shear deformation occurs when the maximum shear resultant (force/length) exceeds a critical value, the yield shear resultant. When the yield shear resultant is exceeded, the membrane flows with a rate of deformation characterized by the plastic viscosity coefficient. The temperature dependence of the yield shear resultant and the plastic viscosity coefficient have been measured over the temperature range of 1040/sup 0/C. Over this range the yield shear resultant does not change significantly (+/ 15%), but the plastic viscosity coefficient changes exponentially from a value of 1.3 x 10/sup 2/ surface poise (dyn s/cm)more » 
Temperaturedependent shear viscosity coefficient of octahydro1,3,5,7tetranitro1,3,5,7tetrazocine (HMX): A molecular dynamics simulation study
Equilibrium molecular dynamics methods were used in conjunction with linear response theory and a recently published potentialenergy surface [J. Phys. Chem. B 103, 3570 (1999)] to compute the liquid shear viscosity and selfdiffusion coefficient of the high explosive HMX (octahydro1,3,5,7tetranitro1,3,5,7tetrazocine) over the temperature domain 550800 K. Predicted values of the shear viscosity range from 0.0055 Pa *s at the highest temperature studied up to 0.45 Pa *s for temperatures near the melting point. The results, which represent the first publication of the shear viscosity of HMX, are found to be described by an Arrhenius rate law over the entire temperaturemore » 
Shear Viscosity Coefficient and Relaxation Time of Causal Dissipative Hydrodynamics in QCD
The shear viscosity coefficient and the corresponding relaxation time for causal dissipative hydrodynamics are calculated based on the microscopic formula proposed in T. Koide and T. Kodama [Phys. Rev. E 78, 051107 (2008)]. Here, the exact formula is transformed into a more compact form and applied to evaluate these transport coefficients in the chiral perturbation theory and perturbative QCD. It is shown that in the leading order calculation, the causal shear viscosity coefficient eta reduces to that of the ordinary GreenKuboNakano formula, and the relaxation time tau{sub p}i is related to eta and pressure P by a simple relationship, tau{submore » 
Explicit expressions of selfdiffusion coefficient, shear viscosity, and the StokesEinstein relation for binary mixtures of LennardJones liquids
Explicit expressions of the selfdiffusion coefficient, D{sub i}, and shear viscosity, η{sub sv}, are presented for LennardJones (LJ) binary mixtures in the liquid states along the saturated vapor line. The variables necessary for the expressions were derived from dimensional analysis of the properties: atomic mass, number density, packing fraction, temperature, and the size and energy parameters used in the LJ potential. The unknown dependence of the properties on each variable was determined by molecular dynamics (MD) calculations for an equimolar mixture of Ar and Kr at the temperature of 140 K and density of 1676 kg m{sup −3}.
