douka: A universal platform of data assimilation for materials modeling
Aoi Watanabe, Ryuhei Sato, Ikuya Kinefuchi +1
A large-scale, general-purpose data assimilation (DA) platform for materials modeling, douka, was developed and applied to nonlinear materials models. The platform demonstrated its…
Practical deviational particle method for variance reduction in polyatomic gas DSMC simulations
Takehiro Shiraishi, Ikuya Kinefuchi
The direct simulation Monte Carlo (DSMC) method is a widely used stochastic particle approach to solving the Boltzmann equation. However, its computational cost remains a major dra…
Gas Adsorption and Diffusion Behaviors in Interfacial Systems Composed of a Polymer of Intrinsic Microporosity and Amorphous Silica: A Molecular Simulation Study
Yuta Yoshimoto, Yuiko Tomita, Kohei Sato +5
We investigate the adsorption and diffusion behaviors of CO2, CH4, and N2 in interfacial systems composed of a polymer of intrinsic microporosity (PIM-1) and amorphous silica using…
Evaluation of gas permeability in porous separators for polymer electrolyte fuel cells: CFD simulation based on micro X-ray computed tomography images
Soichiro Shimotori, Toshihiro Kaneko, Yuta Yoshimoto +4
Pore structures and gas transport properties in porous separators for polymer electrolyte fuel cells are evaluated both experimentally and through simulations. In the experiments,…
Molecular Insights into the Mechanical Properties of Polymer-Fullerene Bulk Heterojunctions for Organic Photovoltaic Applications
Yuta Yoshimoto, Sou Sugiyama, Shuntaro Shimada +3
We investigate the mechanical properties of -conjugated polymeric materials composed of regioregular poly(3-hexylthiophene) (P3HT) and fullerene C using coarse-grained mo…
Relating the thermal properties of a micro pulsating heat pipe to the internal flow characteristics via experiments, image recognition of flow patterns and heat transfer simulations
Chihiro Kamijima, Yuta Yoshimoto, Yutaro Abe +2
We investigate the relationship between the thermal properties of a micro pulsating heat pipe (MPHP) and the internal flow characteristics. The MPHP consists of an eleven-turn clos…
