Abstract

The structure and the properties of the air flow developing when an intake system (in particular, a turbojet engine) operates near a surface are studied. On the basis of numerical calculations, the conditions of onset, the intensity, and the structure of the vortex flow ascending from the surface toward the intake are determined. From an analysis of the particle transport toward the intake by the vortex flow, the main factors responsible for the rise of large particles and objects are determined and the conditions of minimization of the probability of large particles entering the intake are found.
