Bayesian estimation-based information exchange techniques for coupled Navier-Stokes equation and DSMC algorithms

Kongqi donglixue xuebao
In the calculation process of coupled Navier-Stokes (N-S) equation and direct simulation Monte Carlo (DSMC) algorithms, the DSMC method suffers from a limited number of statistical samples.

Simulation of Potassium Condensation by DSMC Method.

Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1994
The evaporation and condensation phenomena of alkali metals are not correctly described by the analysis using the continuum equations, because discontinuity of physical quantities such as temperature at the vapor-liquid interface occurs in the phase change process. The authors apply the direct simulation Monte Carlo (DSMC) method, which is based on the

Synergistic Engineering of Nanostructures via Anodic Aluminum Oxide Templates and Atomic Layer Deposition: Design Principles, Mechanisms, and Applications

Small Structures, Volume 7, Issue 8, August 2026.
Anodic aluminum oxide (AAO) templates combined with atomic layer deposition (ALD) constitute a synergistic platform for engineering functional nanostructures within highly ordered, high‐aspect‐ratio porous architectures. By linking precursor transport modeling, surface chemistry control, and tailored ALD strategies, this review establishes a unified ...

An Internal Model Based—Sliding Mode Control for Open-Loop Unstable Chemical Processes with Time Delay

ChemEngineering, 2023
This paper presents a dynamic sliding mode control (DSMC) for open-loop unstable chemical or biochemical processes with a time delay. The controller is based on the sliding mode and internal model control concepts.

Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1798-1820, July/August 2026.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

Particle-based hybrid and multiscale methods for nonequilibrium gas flows

Advances in Aerodynamics, 2019
Over the past half century, a variety of computational fluid dynamics (CFD) methods and the direct simulation Monte Carlo (DSMC) method have been widely and successfully applied to the simulation of gas flows for the continuum and rarefied regime ...

Disturbance Observer-Based Double-Loop Sliding-Mode Control for Trajectory Tracking of Work-Class ROVs

Journal of Marine Science and Engineering, 2022
The open-frame structure of work-class ROVs results in significant model uncertainties, and its motion is strongly disturbed by the umbilical cable. To address these problems, this article developed a nonlinear disturbance observer-based super-twisting ...

A New Parallel Algorithm of DSMC Method

Procedia Engineering, 2015
AbstractA new parallel algorithm of DSMC method with dynamic load balance implementation was introduced using MPI standard library. The parallel efficiency of the two kinds of parallel modes, peer-to-peer mode and master/slave mode, were investigated, respectively.

Clinical, Radiological, and Immunohistological Distinctions Between Limbic‐Predominant and Typical Alzheimer's Disease: A Systematic Review

Brain and Behavior, Volume 16, Issue 7, July 2026.
Abstract Background Alzheimer's disease (AD) is the most common cause of dementia worldwide and one of the leading causes of morbidity and mortality among elderly people. It is characterized by generalized brain atrophy, especially affecting the hippocampus and medial temporal lobe.

Application of the MCMC Method for the Calibration of DSMC Parameters [PDF]

AIP Conference Proceedings, 2011
A Markov Chain Monte Carlo (MCMC) algorithm was employed to obtain a calibrated distribution for the hard sphere diameter, the VHS reference diameter, and the temperature viscosity exponent of argon, for use in the Direct Simulation Monte Carlo (DSMC) method.
