The analysis of vibration effect on non-isothermal fluid in closed cavity isimportant for planning technological experiments in space. Control andoptimization of these processes critically depend on the understanding ofliquid response to the vibrations. With this aim the theoretical investigationfor infinite plane and cylindrical fluid layers are performed. We investigatedsimple case of the fluid response-thermal vibrational convection in acylindrical fluid layer with rigid conducting boundaries. It is found thatsteady modes of thermal vibrational convection are subjected to variousbifurcations. Bifurcations cause sharp changes in heat transfer. The Lorenzmodel is generalized (GLM) and used to conduct the analysis of bifurcationscaused by the changing of the cavity shape and vibrational Rayleigh number. Theshape of steady-state surface in 3D space of the streamfunction of mean flow,vibrational Rayleigh number and the cavity curvature is found. The numerical 2Dsolution is performed for plane and cylindrical fluid layers. The results ofthe analysis based on the GLM model are compared with the data obtained bydirect numerical simulation. The bifurcation curve with extremum is found.Thus, bifurcations of complex shape could be observed. Comparisons with spaceexperiments and its discussions are presented.
