Asymmetric rotation oscillations effects in free convection task in a square-cross-section cavity with heating from below

Effects of heat convection with heating from below and presence of rotation oscillations were investigated with math modeling method. The task was heat convection in a square-cross-section cavity. Rotation oscillations were generated by rotation of the cavity around inner axis. Symmetric and asymmetric oscillations were considered. Threshold values of parameters were found, these values correspond change of a flow direction in case of stationary and oscillation modes. It was found that deviation from oscillations symmetry leads to threshold parameters values shift.
