S. Though there are going to be a sizable error in the calculation with the resonance peak on the hydrodynamic coefficients within the prospective theory, it has Diversity Library Screening Libraries higher reliability within the calculation with the resonance frequency. Table two summarized the resonance frequency calculated by Equation (five). As shown within the table, the resonant frequency of multi-floating systems with gap spacing of 1 m, 0.5 m, and 0.25 m are 1.79 rad/s, 1.97 rad/s, and 2.08 rad/s respectively. These final results are all in fairly great agreement with all the numerical calculation, the margin of error was 4.five , 5.6 , and three.four , respectively. Which cross-verified the higher prediction accuracy in the modified equation in predicting the resonance frequency. The resonance phenomenon only happens inside a certain frequency variety, and the resonance behaviour is also constrained in a fairly narrow frequency band.Table 2.

The peak resonant frequency of your intermediate module is about twice as higher as that in the two ends, which signifies the hydrodynamic effect in the box within the middle position was located to become the biggest and decreases progressively to both sides. This indicates that the shielding effect plays a non-ignorable function in the hydrodynamic calculation with the many module systems, and the shielding impact mostly affects the values from the hydrodynamic coefficient on the floating bodies. Simultaneously, the hydrodynamic coefficient curves of modules at diverse positions show exactly the same variation. This indicates that while the peak value outcomes are distinctive, the modules at each and every position can completely reflect the hydrodynamic resonance phenomenon by itself, that is representative on the analysis of hydrodynamic interactions within the multi-module technique.J.
