Abstract:
The model of flow in a tornado funnel previously suggested in [1] is updated. The updating of the flow model involves the inclusion of the processes of volume condensation of water vapor. The notation for the input equations is suggested, which is convenient from the standpoint of numerical simulation of processes of heat and mass transfer with due regard for the condensation of moisture within the tornado funnel. The results are given of numerical simulation of two-phase turbulent heat and mass transfer within a tornado funnel. The obtained numerical distributions enable one to identify the range of problem parameters in the case of which an upward flow of moist air may arise, which is sufficient to maintain a quasistationary motion of the tornado.
