Abstract: | The results of the numerical modeling of heat transfer in flows over cubic cavities are presented. The effect of different
parameters of the incident laminar flow, such as the disturbance frequency, the boundary layer thickness, and the main flow
velocity, on the flow stability is investigated. It is shown that the integral heat flux considerably depends on the disturbance
frequencies in the oncoming flow, the frequencies leading to heat transfer intensification being determined by the stability
of the mixing layer between the cavity and the main flow. The calculated integral heat-transfer parameters are compared with
experimental data. The calculated Reynolds-number dependence of the Nusselt number is found to be in good agreement with experiment. |
