“…Such decrease is visually exemplified by the plots, indicative of the simulation's attainment of the set convergence standard. When RMS residual values were observed below the prescribed 0.0001 threshold, the simulation's successful achievement of the desired degree of accuracy and reliability was affirmed [15,16]. This convergence establishes the results as trustworthy and accurate representations of the building's response under simulated wind conditions.…”

Understanding the response of buildings to wind loads is critical, as these forces can generate significant pressure and suction, potentially leading to structural failure if overlooked. This research was focused on examining the effects of openings on triangular-shaped buildings when subjected to high wind load conditions. Utilizing CAD modeling and Computational Fluid Dynamics (CFD) simulations, the analysis was executed through the ANSYS simulation package. Subsequent Fluid-Structure Interaction (FSI) studies were conducted to ascertain shear stress and lateral deformation. The studies encompassed building models both with and without openings, with the evaluation of induced pressure and velocity. The resultant drag on buildings incorporating openings was discovered to be 6679N lower than those without openings. Furthermore, an analysis employing M25 concrete indicated a 33.133% reduction in lateral deformation in buildings with openings as compared to those without. For buildings constructed with M30 concrete, a 32.173% decrease in lateral deformation was observed. Despite the informative findings, it should be recognized that the investigation was confined to a particular range of wind load conditions and did not consider extreme scenarios. Dynamic wind effects and long-term structural behavior were not included in the current analysis. Therefore, while this study elucidates the importance of wind load analysis and structural reinforcement for maintaining building stability, further research is warranted. Such future investigations should consider broader simulation models, encompassing diverse building shapes and wind load conditions, and account for additional influential factors.

“…Taking into account the geometry type and topological consistency of TES units, the model was carefully discretized to ensure optimal accuracy in the analysis [17][18][19][20]. A fine relevance approach was utilized in the meshing process (Figure 3), ensuring that the model was adequately represented in the CFD analysis.…”

Thermal Energy Storage (TES) system has emerged as a promising solution of energy demand and supply management, which stores excess thermal energy and releases it when energy demand is high, making it an efficient and cost-effective energy storage solution when combined with renewable energy sources, such as solar and wind power. This study aimed to evaluate the thermal performance of TES units using Computational Fluid Dynamics (CFD) simulations in the ANSYS CFX software package. After comparing the heat storage capacity of conventional Phase Change Material (PCM) and iron oxide/paraffin wax composite (2%) using industrial residual water, temperature distribution plots and heat flux data were generated in simulations for both cases. Addition of iron oxide nanoparticles significantly improved the heat absorption performance of TES units. Both materials initially exhibited a higher heat absorption rate, which gradually decreased over time. CFD data analysis revealed that iron oxide/paraffin wax material enhanced heat absorption performance by up to 1.3%, which demonstrated the potential of iron oxide nanoparticles in improving the efficiency of TES system and highlighted the advantages of TES system combined with renewable energy sources. By improving heat absorption properties, the incorporation of iron oxide nanoparticles had the potential to increase the lifespan of TES units and significantly reduced maintenance and replacement expenses. This breakthrough, along with the cost savings and energy efficiency offered by TES technology, may encourage its widespread application, thus reducing reliance on fossil fuels and promoting sustainable energy practices.

In heavy-duty vehicles, Exhaust Gas Recirculation (EGR) coolers have been used since 2002 to reduce NOx emissions by recirculating exhaust gases. EGR systems increase fuel efficiency and achieve more thorough combustion, while the EGR cooler, which cools the exhaust gases, is crucial to protect the engine by lowering the combustion temperature. This research evaluates the flow behavior and thermal characteristics of EGR coolers using the k-omega turbulence model. The study compares the effectiveness of two designs of EGR coolers: the single coolant inlet type and the four-inlet type configuration. The CAD design of the EGR cooler is developed in Creo design software, and CFD simulations are conducted using the ANSYS CFX simulation package. The results show that the incorporation of additional coolant inlet tubes improves the EGR cooler's performance. The four-inlet design exhibits higher effectiveness compared to the single-inlet design at every operating temperature. The effectiveness is maximum at an operating temperature of 691K, and the four-inlet design shows 0.02 higher effectiveness than the single-inlet design at an operating temperature of 1058K. The conventional design of the EGR cooler with a single coolant inlet can be substituted with the new proposed design of the EGR cooler with four coolant inlets. The new proposed design of the EGR cooler has higher effectiveness and would enable the reduction of NOx emissions and improve engine efficiency.
