Coherence resonance in a nonlinear aeroelastic system

The data set is for the numerical simulation of stochastic sub-critical pitch-plunge aeroelastic system. The stochastic differential equations (SDEs) are solved in MATLAB. The simulated data is further post-processed to prove the manifestation of coherence resonance in the system. The measures used to establish the phenomenon are power spectral density (PSD), signal-to-noise ratio (SNR), quality factor, correlation time, inter-spike interval (ISI) analysis, which is also provided in the dataset. The dataset also contains the source code used to simulate the system and post-processing codes used to evaluate the measures. Coherence resonance is unexplored in the context of aeroelastic/fluid-structure interaction systems and can pose danger to the safety of the structure. However from the lens of energy harvesting, the amplified power output at the system frequency holds a promising outlook.

Methods
The data was collected by numerically simulating the stochastic system in MATLAB. The post-processing was also performed in MATLAB and a thorough analysis was done to establish the phenomenon of coherence resonance in the stochastic aeroelastic system considered.
