We report on numerical simulation of fluid interface deformations induced by either acoustic or optical radiation pressure. This is done by solving simultaneously the scalar wave propagation equation and the two-phase flow equations using the boundary element method. Using dimensional analysis, we show that interface deformation morphogenesis is universal, i.

- The study introduces a new technique called optorheology that utilizes laser radiation pressure and interferometry to analyze the rheological properties of small-scale soft materials and confined fluids without mechanical contact.
- This method has been validated for measuring surface tension and viscosity in Newtonian liquids and can also assess changes in rheology due to evaporation and concentration in liquid mixtures and suspensions.
- The research further explores the elastic and viscoelastic properties of polymer solutions and examines the effects of laser-induced heating on liquid behavior, suggesting potential new ways to investigate small-scale rheology.
