Abstract
The present article is devoted to the modeling of a gas-air flow at the nozzle of the energy machine designed for the use in the agricultural sector. The machine has an option of secure vibro-drying of grain crops and their control, which increases the drying performance both in the steady-state and transient modes. The article also presents a mathematical model describing acoustic processes in a flow part of the energy machine and suggests the ways to improve them for their safe operation. The authors outline the principles of construction of complex drying systems of aero-acoustic cartography, which allow controlling the parameters of energy machines serving grain crops drying and the climatic parameters depending on the volume of grain dryers. This is very important for productivity increase and automated control in real time, supplemented by methods and means of measurements of gas-dynamic parameters in the flow and at the nozzle of the energy machine. These methods are aimed at increasing information capacity and the level of algorithmic non-destructive condition monitoring of rotor blades as well as providing data in terms of parametric and structural uncertainties of the gas-air flow as controlled by the internal cross-section of the flow part, and the output section of the energy machine. Statistical approaches are used to determine the coordinates of sensors and the recovery error on the example of a model problem for monitoring the radiation field created by a continuous monopole emitter. The possibility of using fiber technologies for vibro-drying of grain is a new contribution to the improvement and effective management of grain drying process.
