The shear viscosity (or viscosity, in short) of a fluid is a material property that describes the friction between internal neighboring fluid surfaces (or sheets) flowing with different fluid velocities. This friction is the effect of (linear) momentum exchange caused by molecules with sufficient energy to move (or "to jump") … See more The classic Navier-Stokes equation is the balance equation for momentum density for an isotropic, compressional and viscous fluid that is used in fluid mechanics in general and fluid dynamics in particular: See more Classic mixing rules for gas Wilke (1950) derived a mixing rule based on kinetic gas theory $${\displaystyle \eta _{gmix}=\sum _{i=1}^{N}{\frac {y_{i}\eta _{gi}}{\sum _{j=1}^{N}y_{j}\varphi _{ij}}}}$$ See more The principle of corresponding states (CS principle or CSP) was first formulated by van der Waals, and it says that two fluids (subscript a and z) of a group (e.g. fluids of non-polar … See more Multi-parameter friction force theory The multi-parameter version of the friction force theory (short FF theory and FF model), also called friction theory (short F-theory), was developed by Quiñones-Cisneros et al. (2000, 2001a, 2001b and Z 2001, 2004, 2006), … See more Elementary kinetic theory In textbooks on elementary kinetic theory one can find results for dilute gas modeling that have widespread use. Derivation of the kinetic model for shear viscosity usually starts by considering a Couette flow where … See more Very often one simply selects a known correlation for the dilute gas viscosity $${\displaystyle \eta _{0}}$$, and subtracts this contribution from the total viscosity which is measured in the laboratory. This gives a residual viscosity term, often denoted See more Phillips (1912) plotted temperature $${\displaystyle T}$$ versus viscosity $${\displaystyle \eta }$$ for different isobars for propane, and observed a similarity between … See more WebAug 5, 2024 · Dynamic viscosity is the force needed by a fluid to overcome its own internal molecular friction so that the fluid will flow. In other words, dynamic viscosity is defined …
