Abstract
A scheme was previously substantiated for the emergence and functioning of ascending swirling flows, which naturally occur in the form of tornadoes and tropical cyclones. It has been shown that the cause of natural twist of an upward air flow in these flows is the rotation of the Earth around its axis. It has also been mathematically proven that the kinetic energy of this rotational motion of air comes only from the kinetic energy of the rotation of the Earth around its axis. It has been established that when the upward motion of air in swirling flows stops, the rotation of the Earth will twist flow to the other side and destroy its rotational motion. Taking into account the previously obtained analytical results, the motion of air in such flows has been numerically simulated. Namely, three-dimensional unsteady calculations simulate flows in a tropical cyclone with gas-dynamic parameters of the flow and its linear dimensions corresponding to the natural observation data. The occurrence of a flow and its transition to a steady state in a specific time have been calculated. The calculations carried out using an explicit difference scheme, which made it possible to parallelize the calculation procedure, have revealed the destruction of a tropical cyclone after a given external energy impact on it and the transition of the air flow in it into unstructured motion in a much shorter time than the time required for the flow to reach a steady state.
