🚤 Riding the waves of innovation in planing hull dynamics 🌊 #MarineEngineering #Innovation We're excited to share our latest research, now available for all the curious minds out there! Our paper offers a look at the hydrodynamic and structural response of planing hulls in irregular waves. 🔍 What We Did: - Conducted a detailed experimental and numerical study comparing traditional and optimized grillage panels of planing hulls. - Used computational fluid dynamics (#CFD) and computational structural dynamics (#CSD) to assess the impact of planing hulls in irregular waves, challenging the norms of structural design methods. - Compared University of Iowa CFDShip-Iowa and Siemens Simcenter STAR-CCM+ results with experimental data. 💡 Key Findings: - Biggest surprise (maybe not for everyone)? The largest impacts on hulls occur not in the highest waves, but in lower waves with deep troughs. - We've shown that numerical simulations outperform current methods in predicting crucial aspects like the vertical acceleration of the center of gravity. - Discussing the American Bureau of Shipping (ABS) practices, we found that while they ensure safety, they tend to be more conservative than needed. 🚀 Looking Ahead: - This research isn't just a conclusion; it's a beginning. It opens doors to more efficient and precise design strategies, moving beyond conservative norms towards innovation. - Our work highlights the need for further exploration in representing irregular wave impacts for efficient and effective structural design. 📖 Read the Full Paper: - Dive into our study here: https://lnkd.in/dyyWtk5e - Find Part I paper on optimization and regular wave studies here: https://lnkd.in/dF6zT8av With Evan J.

I am excited to share that in my second year of my Master's at the University of Tennessee Knoxville, I now have a paper published in the Journal of #EngineeringMechanics, a peer-reviewed scientific journal by #ASCE. I am extremely grateful to my advisor and coauthor Dr. Nicholas Wierschem for his guidance, brilliance, and faith in me for developing this work. Our publication, "Clutching Inerter Damper for Multidegree-of-Freedom Base-Isolated Structures: A Numerical Study" takes a look at a vibration isolation strategy that makes use of a relatively new nonlinear device in structural control, the clutching inerter damper, and compares its performance to other control devices.

I am pleased to share our new article published in International Journal of Thermal Sciences: “Effects of geometry on the thermal-fluid dynamics of a transition water flow in a square heated asymmetric cavity channel”. This is the last article as part of my PhD thesis and it is subsequent to the previous two published. In this work, the S* parameter introduced previously is identified as the penetration capacity of the recirculation in the boundary layer. Additionally, a range of attachment angles for the cavity channel geometry is identified for the most uniform and highest heat transfer performance.

📑 In my recent publication titled "Hybrid Data-driven and Physics-based Simulation Technique for Seismic Analysis of Steel Structural Systems," co-authored with Ali Imanpour, we proposed a new method that combines data-driven models with physics-based simulations. This approach aims to improve the seismic analysis of steel structures by reducing computational costs and mitigating modeling uncertainties.

Transient Charging Process of a Water Storage Tank in ANSYS-FLUENT 💧 🔬 Details: - Archimedes Number = 1.545: This dimensionless number plays a crucial role in understanding the flow dynamics during the charging process. - Numerical Analysis: Using a 2D k-ε turbulence model, the study analyzes how different numerical schemes, like the QUICKEST method, affect the accuracy of thermal stratification predictions in the tank. - Comparison: The results show strong agreement with existing experimental data, validating the use of this approach for studying thermal stratification. 🔗 Full paper: https://lnkd.in/dmni8mZU cc: Mehmet Akif Ezan (YT) #FluidDynamics #ThermalStratification #CFD #ANSYSFLUENT #EnergyEfficiency #Engineering #Simulation

Two articles that we presented at The 14th International Conference on Mechanical Engineering (ICME2023) are now available on SSRN Elsevier as pre-prints. These articles reflect the impacts on open water efficiency of Wageningen-B series marine propellers due to changes in design variables: one article contains the analysis of changing diameter and blade-area-ratio of the propeller while the other article contains that of the pitch-diameter-ratio. Both are parts of our undergrad thesis. In our thesis, along with these two, we also inspected their visual impacts on several hydrodynamic parameters. Adri Das and Rafid Imam were my thesis partners and co-authors of these articles. We also present our gratitude to our supervisor Dr. Shahjada Tarafder Sir for his guidance.
