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...
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...
The medical industry extensively uses nanoparticles for applications such as wound dressing, artificial organ components, drug delivery, tissue engineering, and cardiovascular disease treatment. incorporation of into the base fluid enhances rate heat transmission additionally decreases blood pressure. This study aims to examine effects a new tetra-hybrid nanofluid model, which includes nanoparticles, on flow through stenosed artery with circular shape. Model partial differential equations...
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...
Constructal design is a method that conducts the designer toward flow (e.g., heat flux) architectures have greater global performance. This numerical work uses this to seek for best geometry of complex assembly fins, i.e., an where there cavity between two branches T-Y-assembly fins and additional extended surfaces. The thermal resistance minimized four times by geometric optimization subject following constraints: total volume, volume fin material, cavity, Larger amount material improves...
