Abstract
Numerical simulation of convection of a colloidal binary mixture in a Hele-Shaw cell under vertical vibrations of finite amplitude has been carried out. The boundary of convective instability in a modulated gravity field is found. Bifurcation diagrams are constructed and the concentration distributions of nanoparticles corresponding to various solutions are analyzed. Thermal vibration convective flows are studied in the case of positive thermal diffusion of nanoparticles and their gravitational stratification. It is shown that vibrations, depending on the frequency, can both increase the intensity of the convective flow and weaken it.
期刊介绍：
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
