Techno-economic assessment of long-distance supply chains of energy carriers: Comparing hydrogen and iron for carbon-free electricity generation

Applications in Energy and Combustion Science, 2023
The effective usage of renewable energy sources requires ways of storage and delivery to balance energy demand and availability divergences. Carbon-free chemical energy carriers are proposed solutions, converting clean electricity into stable media for ...

Fluid Simulation with Articulated Bodies [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2010
We present an algorithm for creating realistic animations of characters that are swimming through fluids. Our approach combines dynamic simulation with data-driven kinematic motions (motion capture data) to produce realistic animation in a fluid. The interaction of the articulated body with the fluid is performed by incorporating joint constraints with

Multiscale Lagrangian fluid dynamics simulation for polymeric fluid [PDF]

Journal of Polymer Science Part B: Polymer Physics, 2010
AbstractWe have developed a simulation technique of multiscale Lagrangian fluid dynamics to tackle hierarchical problems relating to historical dependency of polymeric fluid. We investigate flow dynamics of dilute polymeric fluid by using the multiscale simulation approach incorporating Lagrangian particle fluid dynamics technique (the modified ...

Nanofluidics and Nanofluids Shape Oscillation of a Single Microbubble in an Ultrasound Field

Journal of Nanotechnology, 2018
The shape oscillation of a single two-dimensional nitrogen microbubble in an ultrasound field is numerically investigated. The Navier–Stokes equations are solved by using the finite-volume method combined with the volume-of-fluid model.

Virtual-Wall Model for Molecular Dynamics Simulation

Molecules, 2016
A large number of molecules are usually required to model atomic walls in molecular dynamics simulations. A virtual-wall model is proposed in this study to describe fluid-wall molecular interactions, for reducing the computational time.

Machine learning–accelerated computational fluid dynamics [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance Accurate simulation of fluids is important for many science and engineering problems but is very computationally demanding. In contrast, machine-learning models can approximate physics very quickly but at the cost of accuracy.
