Interaction of heterogeneous liquid with flexible wall

Project is focused on the solution of transient interactions of heterogeneous liquid with a flexible wall and experimental verification in large deformations area. Dissipation energy, unsteady hydraulic losses in turbulent flow will be studied considering the cavitation. Interaction with a flexible wall - pressures and shear stresses in the zone of solid/liquid interface will be evaluated. Constitutive models of nonlinear, anisotropic hyperelastic materials will be experimentally identified for flexible tubes. Modal decomposition of vortex structures will be performed on image processing basis, relative to their dissipation function rate. The vortex structures will be experimentally verified by HSC. Methodology using optical methods of PIV, micro PIV for velocity field measurements in the moving area will be developed during project. Liquid interaction with flexible wall will be solved with respect to hydrophobicity when the surface condition does not apply common adhesion of the liquid. A new mathematical model of Navier - Stokes equations derived by project authors will be used.
