Projects in Computational Engineering

December 2022 – February 2023

As a FEA engineer, I was engaged in a project to perform a structural analysis of a fiber-reinforced plastic (FRP) tank with the dimensions of 14 meters in height and 7 meters in diameter for a client who is a fiberglass manufacturer. The aim of this project was to assess the structural integrity and stability of the FRP tank design, in order to provide the client with the information they need to make informed decisions about the production of this tank. In this project, I am assisted with my partner.

To perform the analysis, we used state-of-the-art finite element analysis (FEA) software and computational tools to evaluate the structural performance of the tank under various loads and conditions. This allowed us to assess the stress and deformation behavior of the tank and to identify any areas of concern that might need to be addressed in the design.

The results of this project are going to be successful, and I am providing the client with a comprehensive structural analysis report detailing the findings of our work. The report included information about the structural performance of the FRP tank under various loads, including internal hydrostatic of fluid, wind, and seismic loads. There might be recommendations for any changes or modifications that might be needed to improve the structural integrity of the tank.

The client is pleased with my work of this project and trust me to give them the information to be very useful in their decision-making process. They will able to use our findings to evaluate the feasibility of producing the FRP tank and to make informed decisions about its design and production.

This project demonstrates my expertise in the area of finite element analysis and my ability to provide valuable insights and recommendations to clients. I am confident that my skills and experience will continue to help me provide high-quality engineering services to clients in the future.

November–December 2022

As a CFD/FEM engineer in freelancing for a project focused on the analysis of the vibration of a pipe due to internal fluid flow, I was tasked with investigating the effect of fluid flow on the structural integrity of a pipe. The aim of this project was to understand how fluid flow within a pipe can cause vibrations and how these vibrations can impact the overall performance and safety of the pipe, in order to provide valuable insights for the client's further research. To accomplish this goal, I used both computational fluid dynamics (CFD) and finite element analysis (FEA) in ANSYS software. These powerful simulation tools allowed me to analyze the fluid flow within the pipe and to calculate the resulting stresses and strains on the pipe structure.

The results of this project were successful, and I was able to provide valuable insights into the behavior of pipes under fluid flow. My findings demonstrated the importance of considering the potential for vibrations when designing pipes for fluid flow and highlighted the need for robust structural analysis to ensure that pipes can withstand these dynamic loads.

Working on this project was a challenging but rewarding experience, as it allowed me to apply my skills in simulation and analysis to a real-world problem. The successful completion of this project highlights my ability to use advanced engineering tools to solve complex problems and to provide valuable insights.

August–October 2022

As an associate researcher in a lecturer's project, my research partner and I were involved in the analysis of the frequencies of vibration of NACA 0015 on a fishing boat. The aim of this research was to study the vibration behavior of a NACA 0015 airfoil applied in the design of a fishing boat. To conduct this research, several methods were used, including computational fluid dynamics (CFD), finite element analysis (FEA), and modal analysis. These methods allowed us to analyze the vibration behavior of the airfoil and its impact on the performance of the fishing boat.

As a result of this research, we were successful in obtaining findings and producing a comprehensive report. The report provides valuable insights into the relationship between the frequencies of vibration and the design of NACA 0015 airfoils on the boat. Our findings will contribute to development of more effective and efficient designs of airfoil applied to a fishing boat, helping to improve their efficiency and safety.

Working on this research project completing three months of progress (August 2022 to October 2022) was a valuable experience for me, as I was able to apply my skills and knowledgein computational engineering. The use of advanced computational methods allowed us to gain a deeper understanding of CFD/FEA and modal analysis, and the results of this research will have a positive impact on the field of naval architecture.

January–June 2022

The Geometric Effect of Bulbous Bows to The Hydrodynamic and The Probability of Slamming on Catamaran research project aimed to investigate the impact of bulbous bows on the hydrodynamic performance and the probability of slamming in catamaran vessels. Slamming is a critical issue in ship design and can lead to structural damage, loss of cargo, and increased maintenance costs. To conduct this research, the method of computational fluid dynamics (CFD) and multibody dynamics were used in the hydrodynamic analysis. This method allows us to set the simulation of fluid flow around a ship, providing insight into the ship's hydrodynamic performance.  The researchers have experienced in ship analysis as civitas academica for years. They are Dr, Wiwin Sulistyawati, S.T., M.T. the lecturer and also the head of Department of Naval Architecture Engineering; Purwo Joko Suranto, S.T., M.T. the lecturer of Naval Architecture Engineering; and obviously me (Erlangga Saputra, S.T.) the former student of Naval Architecture Engineering.

The result of the research was submitted to a paper in an international journal named "CFD Letters" and was presented at the International Conference on Computational Heat Transfer and Fluid Mechanics (ICCHTFM) held on July 30-31st, 2022 in Putrajaya, Malaysia. This presentation provided an opportunity for us as the researchers to share our findings with an international audience and receive feedback from experts in the field.

The outcome of this research project contributes to the body of knowledge in the field of naval architecture by providing valuable insights into the impact of bulbous bows on the hydrodynamic performance and the probability of slamming in catamaran vessels. The findings of the research will help ship designers to make informed decisions about the geometric effects of bulbous bows and the use of it in the design of catamaran vessels, ultimately leading to safer and more efficient ships. The successful publication of the results and presentation at a prestigious international conference demonstrated the significance and impact of my research in the field of naval architecture and fluid dynamics.
