Influence of an interfacial heat release on nonlinear convective flows in a laterally heated two-layer system

The influence of the interfacial heat release on nonlinear convective flows, developed under the joint action of buoyant and thermocapillary effects in the 47v2 silicone oil-water system, is investigated. The system filling a closed cavity is heated from the lateral wall. The wide range of the modified Grashof number values, corresponding to heat sources and heat sinks at the interface, is considered. It is shown that the presence of the interfacial heat release can change the sequence of bifurcations and lead to the appearance of specific oscillatory regimes in the system.
