The project is focused on the study of second viscosity of liquids with specialization to the pressure pulsation in the hydraulic systems. The methodic comes out the disequilibrium thermodynamics. Using the thermodynamics laws will be derived the irreversible stress tensor and will be defined two viscosities in the dependence of the strain rate deviator tensor and the strain rate spherical tensor. By the pressure wave propagation will be set the volume viscosity of chosen fluids; especially water, air and mineral oil. The constitutive equations will be adding into the software for the fluids pressure pulsations. (en)
