The role of V–V processes in vibrationally excited CO systems in the longitudinal and transverse flow chemical lasers is studied. Initial vibrational energy distributions of CO formed by the O + CS reaction are deduced from chemiluminescent data using calculated values of the vibration energy exchange probabilities. The time evolution of the population distributions is then obtained by computer simulation. The results are compared with experimental measurements. The effects of excess oxygen and of "cold" CO on the population distributions are also discussed.

Abstract This paper explores a 2:1 internal resonance of a bistable vibration energy harvester (BVEH) to enhance the harvesting performance. Two linear natural frequencies are tuned to meet the nearly commensurate ratio, i.e., 1:2. Thus, the 2:1 internal resonance could be activated when the first mode is directly excited under the same vibration frequency as the first linear natural frequency. The amplitude-frequency responses under small vibration amplitudes are obtained through the multi-scale method. The analytic results reveal the double-jumping characteristics, which could expand the bandwidth of the BVEH. Among them, an intriguing “flower pattern” amplitude-frequency curve is observed. Besides, the frequency spectrums are introduced to demonstrate the mode coupling and energy exchange between the first two modes. With small vibration amplitude, only intra-well responses could be obtained, and the energy exchange between modes obeys strict commensurate relation, i.e., 2:1. However, it does not obey the 2:1 ratio when the inter-well responses are activated, and the energy transfers to several low-frequency modes which results in a chaotic inter-well response. Afterward, the bifurcation diagrams and basin-of-attraction maps are explored by the numerical method to develop insights into the nonlinear responses of the BVEH. The results quantitatively prove the enhancement of the inter-well responses by internal resonance, and the chaotic inter-well response dominates the nonlinear behaviors.
