“…The simulation software program Fluent is widely employed in diverse fields, e.g., aerospace, biology, and energy [18,19], as it offers a variety of grid types (including structural and non-structural), which can be applied before executing the simulation; physical models, such as laminar flow, turbulence, and transmission models; and different types of boundary conditions, e.g., for the inlet/outlet and wall. When executing the numerical simulation, the user can monitor the change in each physical quantity, e.g., speed, temperature, or pressure, in real time while the software performs the calculation according to a set of predefined constraints.…”

The splitter is an important component of water-based cooling systems used to extract heat from computer boards. In the present study, the flow characteristics of a 16-splitter structure were numerically simulated and compared with experimental results to verify the reliability of the numerical simulation method. Accordingly, the concept of splitter structural coefficients was proposed. Based on the results of this study, we recommend a selection range of 5 ≤ k ≤ 6 for the structure factor k of the splitter; after optimization, the maximum deviation of the splitter outlet flow was reduced from the original value of 100% to 8.3%.

“…Our goal is to enrich the understanding of various greenhouse ventilation strategies to assist in their design. This endeavor is driven by the need to fill gaps in existing literature concerning natural ventilation in greenhouse environments [2,3]. One study enhances this understanding by analyzing the impact of roof openings on heat transfer in tunnel greenhouses, emphasizing the importance of natural ventilation in managing internal climates [4].…”

This study addresses the pressing need for energy-efficient greenhouse management by focusing on the innovative application of natural ventilation. The primary objective of this study is to evaluate various ventilation strategies to enhance energy efficiency and optimize crop production in agricultural greenhouses. Employing advanced numerical simulation tools, the study conducts a comprehensive assessment of natural ventilation's effectiveness under real-world conditions. The results underscore the crucial role of the stack effect and strategic window positioning in greenhouse cooling, providing valuable insights for greenhouse designers. Our findings shed light on the significant benefits of optimized ventilation and also offer practical implications for improving greenhouse design, ensuring sustainable and efficient agricultural practices. The study demonstrated energy savings in cooling from November to April, with a maximum saving of 680 kWh in March, indicating the effectiveness of strategically positioning windows to leverage the stack effect. This approach enhances plant growth and reduces the need for costly cooling systems, thereby improving overall energy efficiency and lowering operational expenses.
