Abstract:
Experimental measurements of the dynamic coefficient of air viscosity were done. Numerous other related values such as the kinematic coefficient of air viscosity, the mean free path and the mean thermal square velocity of air molecules were determined. The dependence of the air dynamic viscosity coefficient on temperature was also obtained. It allowed us to determine the Sutherland’s corrections and to estimate the dimension of air molecules and the temperature gradients of the dynamic and kinematic coefficients of the air viscosity. The determined values were compared to the similar theoretic

Coefficient of dynamic viscosity (η) for uniaxial rectangular bar of steel is calculated using creep simulation in Ansys. Norton Secondary creep law with coefficients at 600 ᵒC is used.

Isotropic damage parameter (D) based on the volume fraction of damaged elements is used to formulate a linear relation between the coefficient of viscosity and D.

Nanofluids are formed by solid particles with nano-sized dimension (1-200 nm) dispersed into common fluids.

In the last years, an exponential increase of publications on nanofluids is occurred.
