研究紹介(About my Research)
My research focuses on the numerical investigation of sloshing phenomena in fluid-containing tanks and the potential for energy harvesting using flexible piezoelectric nanogenerators (PENGs). In particular, I explore how sloshing-induced motion, which is typically considered a negative effect in marine and storage applications, can be transformed into a source of renewable energy.
In our published work in Results in Engineering (ScienceDirect), titled:
🔗 Numerical study on the reduction effect of the sloshing phenomenon and energy harvesting using a flexible piezoelectric nanogenerator - ScienceDirect,
We conducted 2D SPH-based simulations to evaluate how flexible structures with integrated PENGs not only mitigate violent fluid oscillations but also generate measurable electric power. We investigated the effects of baffle design, excitation frequency, and structural flexibility on both sloshing suppression and energy output.
A follow-up study was presented at the International Ocean and Polar Engineering Conference (ISOPE) under the title:
🔗 Energy Harvesting from Sloshing Motion of a Fuel Ship Using Flexible Piezoelectric Nanogenerator Device | International Ocean and Polar Engineering Conference | OnePetro.
This study extended the numerical modeling into a realistic 3D environment, simulating sloshing within fuel tanks of a ship in motion. We proposed the integration of PENGs in flexible internal structures to harvest energy from unavoidable ship-induced sloshing, offering a sustainable power source for onboard systems.
Together, these studies contribute to next-generation ship design, particularly for fuel carriers, where managing sloshing is critical and where energy recovery from internal dynamics can support decarbonization efforts in maritime systems.

Results in Engineering, 25(104543) , https://doi.org/10.1016/j.rineng.2025.1045432590-1230 概要はこちら(Description) This study presents the use of flexible perforated baffles made from piezoelectric nanogenerator (PENG) materials to achieve dual functionality: reducing sloshing motion and harvesting energy within ship tanks. Both experimental and numerical investigations—conducted using the Smoothed Particle Hydrodynamics (SPH) method—demonstrate that PENG-based baffles are effective in: • Suppressing sloshing amplitude • Converting fluid motion into usable electrical power The proposed approach offers a sustainable solution for marine systems by integrating sloshing mitigation and energy harvesting into a single structure. Numerical simulations show strong agreement with experimental data, confirming the accuracy and reliability of the SPH-based modeling. These findings suggest a promising pathway for applying PENG-integrated structures in real-world ocean engineering, particularly to improve ship stability and promote onboard energy efficiency.
