A numerical model to simulate the aerodynamic olfactory effect of the gas-sensitive UAV

Abstract

The attempts of robot implementations and simulation framework designs for the solution to three dimensional robot active olfaction problems are reviewed. A numerical model is proposed to dynamically simulate the gas dispersion under the air flow disturbance introduced by the rotating propellers of gas-sensitive unmanned aerial vehicles (UAVs). The model is an interdisciplinary approach that integrates free vortex methods and statistical approaches. Both velocity field and gas dispersion calculation processes are described. Theoretically the model is suitable for the simulation of all gas-sensitive UAVs which gain thrust with propellers.
