摘要: A thermodynamics is introduced for fluids subjected to a constant shear. The theory based primarily on the results of computer simulations using technique homogeneous shear nonequilibrium molecular dynamics applied system 108 Lennard‐Jones particles. It supported qualitatively by several authors other systems. rate γ enters explicitly into description fluid: equation state p = p(V,T,γ) and thermodynamic dE TdS −pdV+ζdγ, where ζ function. Using relations found previously be valid wide range γ: p0+p1γ3/2 E E0+E1γ3/2, can checked numerically consistency consequences, such as stability criteria criteria, verified. indicate that phase changes are influenced when
