Experimental Verification of an Aerodynamic Olfactory Effect Model for the Simulation of Gas-Sensitive Rotorcrafts

This paper described an experiment which was designed to validate the effectiveness of an aerodynamic olfactory effect model for the simulation of gas-sensitive rotorcrafts. The model simulates the rotor wakes using free vortices and calculates the distortion of the gas plume using filament based plume model. We designed an experiment in which a camera recorded the distortion of the smoke plume, and proposed a practical video processing routine to extract the smoke dispersion trajectory. Then the trajectory was compared with the simulated one to validate the model. Results showed that this aerodynamic olfactory effect model is a credible way to simulate odor diffusion process under the influence of quadrotor.
