###### Abstract
For the study, the results showed that the free surface's elevation depends on the relative wavelength. More recently, [PERSON] et al. [10] studied a device in a three-dimensional experimental and numerical form, following the continuity of the works presented by the previous authors. OWC devices were subjected to different wave heights and periods. With the investigation, it was possible to identify that the three-dimensional modeling of the offshore OWC device overestimates the global energy extraction efficiency, especially for high wave frequencies compared to the experimental model. [PERSON] et al. [11] evaluated OWC devices employing the VOF computational model in strictly numerical works. Geometric variations and different wave characteristics for two-dimensional and three-dimensional cases were studied. The results were compared with experimental data to validate the chosen computational model. [PERSON] et al. [12] presented a computational model for the two-dimensional simulation of OWC devices, subject to a Pierson-Moskowitz wave spectrum. The objective of the work was to obtain recommendations regarding temporal discretization and a computational mesh with sufficient refinement to produce results with greater precision with less computational effort. The results indicated that the theoretical recommendations are based

Afterward, [PERSON] et al. [13] presented an investigation of an OWC device installed on the south coast of Brazil. The authors used FLUENT software based on the finite volume method (FVM) and the model that solves the Reynolds averaged Navier-Stokes (RANS) equation. The device is equipped with a Wells-type turbine with pressure control and rotation speed regulation. [PERSON] et al. [14] presented a two-dimensional numerical study to analyze the energetic viability of wave potential on the Brazilian coast. Thus, numerical simulations were performed to determine the waves' significant height and power ratio using a two-dimensional TOMAWAC spectral model. The results show that in areas close to the coast, the average power rate reached values of 15 kW/m, while offshore values achieved 18 to 20 kW/m, being more frequent in the South-Southeast Brazilian platform. Even with several contributions to the geometry design of OWC devices, the use of Constructal Design for the geometric evaluation of this type of WEC has been gradually increasing. Constructal Design is based on the Constructal Law, which was used in its early years as a design tool to increase engineering systems' performances or describe a natural phenomenon; so, the Constructal Law concerns the changes undergone by any flow system [15]. Constructal Law states that for a finite flow system to persist in time (to survive), its configuration must freely change in time so that it provides easy access to its currents. The geometry of the structures must be reconfigured to obtain maximum use with minimum energy expenditure [16]. The Constructal Design method had been used to guide the design in several areas of knowledge. For example, [PERSON] et al. [17] presented wide applications of the association of the method to different areas of study. The versatility of the method was demonstrated, and the most diverse applications and interpretations were given with examples, such as heat exchangers, other renewable energy sources, such as earth-air heat exchangers and solar chimneys, and even the mechanics of solids have been illustrated. The following authors proposed works involving OWC and the Constructal Design method, in which the Exhaustive Search optimization method is associated to analyze all the proposed geometric variations. A two-dimensional approach was used based on the FVM using VOF to deal with the water and air interaction in multiphase problems with regular waves as a computational model. [PERSON] et al.
