We study flows and interface deformations produced by the scattering of alaser beam propagating through non-absorbing turbid fluids. Light scatteringproduces a force density resulting from the transfer of linear momentum fromthe laser to the scatterers. The flow induced in the direction of the beampropagation, called 'optical streaming', is also able to deform the interfaceseparating the two liquid phases and to produce wide humps. The viscous flowtaking place in these two liquid layers is solved analytically, in one of thetwo liquid layers with a stream function formulation, as well as numerically inboth fluids using a boundary integral element method. Quantitative comparisonsare shown between the numerical and analytical flow patterns. Moreover, wepresent predictive simulations regarding the effects of the geometry, of thescattering strength and of the viscosities, on both the flow pattern and thedeformation of the interface. Finally, theoretical arguments are put forth toexplain the robustness of the emergence of secondary flows in a two-layer fluidsystem.
