A study on the dynamic behaviors of water droplets impacting nanostructured surfaces
AIP Advances, 2011 We have investigated the influence of impact velocity and intrinsic surface wettability of nanostructures on the impact dynamic behaviors of water droplets on nanostructure surfaces.

Compressible and immiscible fluids with arbitrary density ratio [PDF]
arXivFor the water-air system, the density ratio is as high as about 1000; no model can fully tackle such a high density ratio system. Here, we present an alternative theory for the density evolution equations in computational fluid dynamics, differing from the concept of Navier-Stokes and Euler equations. Our derivation is built upon the physical principle

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Bubble visualization in a simulated hydraulic jump [PDF]
arXiv, 2013 This is a fluid dynamics video of two- and three-dimensional computational fluid dynamics simulations carried out at St. Anthony Falls Laboratory. A transient hydraulic jump is simulated using OpenFOAM, an open source numerical solver. A Volume of Fluid numerical method is employed with a realizable k-epsilon turbulence model. The goal of this research

Introduction to Computational Fluid Dynamics [PDF]
International Journal of Information Science and Computing, 2016 Computational fluid dynamics (CFD) is an essential tool, which usually uses numerical methods for developing approximations of the governing equations of fluid mechanics in the fluid region of interest. It sufficiently predicts fluid flow, heat transfer, mass transfer, chemical reactions, andrelated phenomena by solving the mathematical equations which

Vid2Fluid: 3D Dynamic Fluid Assets from Single-View Videos with Generative Gaussian Splatting [PDF]
arXivThe generation of 3D content from single-view images has been extensively studied, but 3D dynamic scene generation with physical consistency from videos remains in its early stages. We propose a novel framework leveraging generative 3D Gaussian Splatting (3DGS) models to extract 3D dynamic fluid objects from single-view videos.

Revealing essential dynamics from high-dimensional fluid flow data and operators [PDF]
arXiv, 2019 We consider concepts centered around modal analysis, data science, network science, and machine learning to reveal the essential dynamics from high-dimensional fluid flow data and operators. The presentation of the material herein is example-based and follows the author's keynote talk at the 32nd Computational Fluid Dynamics Symposium (Japan Society of
