“…The software utilizes a mathematical approach to simulate the machining and manufacturing of thin‐walled impeller blades, taking into account the combined effects of material removal, machine tool dynamics, and cutting forces of the cutting tool and workpiece. Finnegan et al 83 developed a model for tidal turbine 1 MW power generation nacelle with full‐size fiber‐reinforced composite blades through numerical modeling, advanced manufacturing techniques, and state‐of‐the‐art structural testing techniques, which yielded some results.…”

The micro turbine engine (MTE) plays a vital role in the aerospace sector. However, traditional research and design models no longer suffice to accommodate the highly complex operating conditions of the MTE. Therefore, this paper briefly analyzes the concept and development process of digital twin technology and integrates it into the research and design of the MTE. This integration takes into account the recent leapfrog developments in information technology and digital intelligence technology. Utilizing digital twin technology to model the core components of the MTE allows for effective structural optimization, online monitoring, and timely problem detection in support of extending the overall lifespan of the engine. Multiple algorithms are used throughout the development, design, and usage phases of each component to merge into a cohesive whole, providing robust support for the MTE's overall development, production, and manufacturing. Digital twin technology facilitates accurate performance prediction, reliability evaluation, and advanced design optimization for the MTE. This, in turn, reduces the design cycle and research design cost more effectively. Lastly, we propose the future application and development trend of digital twin technology in the core components of the MTE.

“…Simulasi juga dilakukan untuk ketika aliran turbulen melewati turbin (Zhu, 2021). Selain itu, metode simulasi juga dilakukan untuk mengetahui noise atau kebisingan dari aliran yang melintasi turbin (Lloyd, 2014) dan juga digunakan untuk mengetahui kekuatan struktur turbin (Finnegan, 2022). Hasil simulasi pada turbin arus laut digunakan untuk mengetahui distribusi kecepatan fluida (William, 2015) dan distribusi pressure coefficient (Alipour, 2020) Garis 3 yaitu berada pada posisi tengah turbin atau z= 0.5m, dan garis 4 berada di posisi paling bawah mendekati permukaan dasar atau z= 0.7m.…”

This study simulated the characteristics of the fluid flow that passes through the Darrieus turbine before installation and testing were carried out. The purpose of knowing the flow characteristics can determine the profile and position of the maximum speed so that the design and placement of the turbine can be improved. The research method was carried out using dynamic fluid computational simulations in three-dimensional form with steady state conditions, discretization using second-order, with convergent conditions when it reached 10-6. The simulation results show that the position of the flow above the turbine had the lowest value because the fluid flowed relatively without disturbance which caused the velocity to had a value almost the same as the incoming fluid velocity. The fluid velocity increased when it was in line 2 and line 3 or across the turbine. This was due to the turbulence generated by the rotation of the turbine. While the speed on line 4 or below the turbine had a lower value than line 2 and line 3. This was due to the position below the turbine so that the turbine rotation did not have an impact on speed. At the four line positions the velocity increased at Y=0.7 m or when the fluid hits the turbine. This increase in fluid velocity was expected to turn the turbine. The results also included the flow distribution in the form of a streamline in several positions where the flow that was in contact with the channel wall had a low velocity value due to friction with the wall.

In the context of harvesting tidal stream energy, which is considered a promising source of renewable energy due to its high energy density, stability, and predictability, this paper proposes a review-based roadmap investigating the use of data-driven techniques, more specifically machine learning-based approaches, to detect and estimate the extent of biofouling in tidal stream turbines. An overview of biofouling and its impact on these turbines will be provided as well as a brief review of current methodologies and techniques for detecting and estimating biofouling. Additionally, recent developments and challenges in the field will be examined, while providing several promising prospects for biofouling detection and estimation in tidal stream turbines.
