Figure 15 shows the variation of the accumulated hydropneumatic power for all studied cases. With the increase in the number of coupled devices, there is an increase in hydropneumatic power. This fact can

As in the other analyzed quantities, the available hydropneumatic power presents its highest values in each of the configurations studied in the range of \(0.25<Hn/Ln<0.50\). The increase in the power indicates that more energy is being converted into the device, so with five chambers coupled, the maximum accumulated hydropneumatic power is greater than the other cases. In addition, the hydropneumatic power shows a maximum point, but after it starts to decrease. This behavior is due to the hydropneumatic chamber's geometry. With the increase in the chamber, the greater its height and the smaller its length, and the lesser energy is converted. Figure 16 shows the results of the highest accumulated hydropneumatic power for all cases. When comparing the cases of three and four CC, it is possible to identify a slight power difference noticeable that the case with three CC of higher performance presents a greater accumulated power than the case with four chambers. \[\int\rho_{air}\overset{\rightarrow}{v}_{air}\cdot d\overset{\rightarrow}{A} =\sum_{t=1}^{n}\left(\rho_{air}^{t}\right)\overset{\rightarrow}{v}_{air}^{t} \overset{\rightarrow}{(A_{t})} \tag{17}\]1 Available hydropneumatic power from the highest performing cases. \[\int\rho_{air}\overset{\rightarrow}{v}_{air}\cdot d\overset{\rightarrow}{A} =\sum_{t=1}^{n}\left(\rho_{air}^{t}\right)\overset{\rightarrow}{v}_{air}^{t} \overset{\rightarrow}{(A_{t})} \tag{17}\]2 Accumulated available hydropneumatic power in each coupled device. The results of Figure 16 show that the addition of five coupled devices converts more hydropneumatic power than the other cases with a lower number of coupled chambers. The geometric analysis of the structure determines the configuration that presents the maximum hydropneumatic power converted for all the analyzed cases. It is a helpful tool in construction projects of devices converting the energy of the sea waves in the function of its large structures. Using the Constructal Design method associated with the exhaustive search method was decisive for analyzing the data. The geometric variation defined through the method and the analysis of degrees of freedom and performance indicator results showed the available power converted when only cases ranging from one to five coupled hydropneumatic chambers were analyzed. The case with the highest performance within the displayed range, with five chambers coupled and geometry with the ratio \(Hn/Ln=0.2613\) (\(Hn=4.1335\) m and \(Ln=15.8219\) m), led to a hydropneumatic power of \(\{P_{hyd}|_{opt}=30.8\) kW. The lowest performance case has one chamber, and the ratio \(Hn/Ln=0.2613\) (\(Hn=4.1335\) m and \(Ln=15.8219\) m) conducting to a hydrodynamic power of \(\{P_{hyd}|_{opt}=200\) W.  
Another aspect obtained through the results presented is a theoretical recommendation using the parameters height and wavelength referenced in the numerical investigation. The geometric configurations that present the maximum conversion are within the range \(16\) (\(H/\lambda\)) \(<Hn/Ln<32\) (\(H/\lambda\)). This range is the theoretical recommendation for the cases of coupled devices, based on the interval that led to the highest performance for each number of coupled devices (\(0.25<Hn/Ln<0.50\)).
