The results of numerical simulation of the heat transfer in the streamlined cubic cavity are presented. The influence of various laminar incoming flow parameters on the flow stability is investigated. It is shown, that the integral heat flux strongly depends on the perturbation frequency in the incoming flow. The frequency range, leading to the heat transfer intensification, is determined by the stability of the shear layer between the cavity and the main flow. The role of the rotation angle of the cavity relative to the direction of the incoming flow on the heat transfer is investigated.
