In this paper, we rely on the Constructal method to optimize geometry of a Y-shaped cavity embedded into solid conducting wall. The structure has four degrees freedom. objective is minimize global thermal resistance between and cavity. optimization procedure demonstrated that for larger solids, shaped as T led minimization resistance, while opposite effect observed tall where optimal shapes are reached when bifurcated branches deeply penetrates in vertical direction, according principle...
In the present work constructal design is employed to optimize geometry of a convective, Y-shaped cavity that intrudes into solid conducting wall. The main purpose investigate influence dimensionless heat transfer parameter over optimal geometries cavity, i.e., ones minimize maximum excess temperature (or reduce thermal resistance domain). search for best has been performed with help genetic algorithm (GA). For square solids (H/L = 1.0) results obtained an exhaustive (which based on solution...
The current numerical work conducted a geometrical investigation of forced convective flows over staggered arrangement four cylinders applying constructal design. main objectives are to determine designs maximizing the Nusselt number (NuD) and minimizing drag coefficient (CD) at three distinct Reynolds numbers (ReD = 10, 40, 150) considering Pr 0.71. problem involves two constraints: cross-sectional area occupation arrangement, degrees freedom: ST/D, SL1/D SL2/D. These represent ratios...
This study presents a numerical evaluation of Horizontal Rectilinear Earth–air Heat Exchanger (EAHE), considering the climatic and soil conditions Viamão, Brazil, subtropical region. The Constructal Design method, combined with Exhaustive Search, was utilized to define system constraints, degree freedom, performance indicators. freedom characterized by aspect ratio between vertical horizontal lengths elliptical cross-section duct (H/L). indicators for EAHE configurations were assessed based...
The climate crisis represents one of the greatest contemporary global challenges, requiring actions to mitigate its impacts and sustainable solutions meet growing demands for clean energy coastal protection. Therefore, study devices such as submerged plate (SP), which simultaneously acts a breakwater (BW) wave converter (WEC), is especially relevant. In this context, present numerical compares efficiency an SP device under regular waves across different geometric configurations considering...
Among the various potential renewable energy sources, sea waves offer significant potential, which can be harnessed using wave converter (WEC) devices such as overtopping converters. These operate by directing incident up a ramp into reservoir. The water then passes through turbine coupled with an electrical generator before returning to ocean. Thus, present study deals geometrical evaluation of WEC, where influence ratio between height and length device (H1/L1) on amount mass (M) that...
Steel plates have wide structural applications in various engineering sectors due to their combination of lightness, efficiency, and high load-bearing capacity. When stiffeners are added these structures, the deflections can be significantly minimized. In this study, hat-stiffened having box-girder with a trapezoidal shape, positioned longitudinally along plate, considered evaluate influence on maximum central deflection structure. The analyses work carried out using ANSYS Mechanical APDL...

The size of ships has increased considerably in recent decades. This growth impacts the stress magnitude bottom hull plates, which constantly suffer from biaxial compression and lateral water pressure, potentially leading to buckling. Adding stiffeners is an effective alternative increase mechanical buckling resistance if placed a proper way. Several researchers have investigated influence on plates under different loading conditions. However, behavior combined pressure not yet been widely...
