  opening ratio
    Based on Bernoulli equation, nonlinear differential equation for dynamic internal pressure is derived and random vibration theory combined with iteration algorithm is used to obtain the solution. Numerical examples are provided to investigate frequency response characteristic of internal pressure and the influences of opening ratio, opening number and opening position on fluctuating internal pressure.

  opening ratio
The mechanism of internal pressure fluctuation is obtained by using the proposed method in the frequency domain and a new equivalent opening ratio is defined to evaluate internal pressure fluctuation.
      
Helmholtz resonance is likely to occur when the equivalent opening ratio is adequately high, and controlling individual opening dimension is an effective strategy for avoiding Helmholtz resonance in engineering.
      
The technique is illustrated in the case of a plane turbulent impinging twin-jet with an opening ratio of 10.
      
It is also demonstrated that large chirp and mismatch of the phase inversion reduces the eye opening ratio (EOR) which can seriously affect the performance of the wavelength converter to be used as a sub-system component in all-optical networks.
      
The effects of the feed rate, the gas flowrate and the opening ratio and hole diameter of the perforated plates on the operating stability of the fluidized bed were examined.
