Vortex-Induced Vibrations of an Elastic Micro-Beam with Gas Modeled by DSMC

open access: yesSensors, 2023
The fluid–structure interaction is one of the most important coupled problems in mechanics. The topic is crucial for many high-technology areas. This work considers the interaction between an elastic obstacle and rarefied gas flow, seeking specific ...

Rarefied flow regime of an underexpanded supersonic jet [PDF]

open access: yesE3S Web of Conferences, 2023
The results of a numerical study of a supersonic underexpanded jet flowing from a conical nozzle into a rarefied environment are presented. The modeling was performed by the direct simulation Monte Carlo method.

DSMC–LBM mapping scheme for rarefied and non-rarefied gas flows [PDF]

open access: yesJournal of Computational Science, 2016
We present the formulation of a kinetic mapping scheme between the Direct Simulation Monte Carlo (DSMC) and the Lattice Boltzmann Method (LBM) which is at the basis of the hybrid model used to couple the two methods in view of efficiently and accurately simulate isothermal flows characterized by variable rarefaction effects. Owing to the kinetic nature

An open source, parallel DSMC code for rarefied gas flows in arbitrary geometries [PDF]

open access: yes, 2010
This paper presents the results of validation of an open source Direct Simulation Monte Carlo (DSMC) code for general application to rarefied gas flows. The new DSMC code, called dsmcFoam, has been written within the framework of the open source C++ CFD ...

Nearly Free Molecular Heat Transfer from a Sphere [PDF]

open access: yes, 1968
Consider a sphere immersed in a rarefied monatomic gas with zero mean flow. The distribution function of the molecules at infinity is chosen to be a Maxwellian. The boundary condition at the body is diffuse reflection with perfect accommodation to the

Numerical simulation of a rarefied gas jet emanating from an ion-optical system of the microthruster [PDF]

open access: yesОмский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение"
A jet of ionized rarefied gas escaping from an ion-optical system of a prototype resonator RF-ion thruster into the surrounding space with low background pressure is considered.

Construction and Testing of a Rarefied Gas Flow Facility [PDF]

open access: yes, 1967
A low-density gasdynamic facility, suitable for measurement of mass flow through small (approximately 1 mm diameter) nozzles, tubes, and orifices, was designed and constructed. The system is capable of producing and measuring mass flows at 100:1 upstream/

A Proposal for Long-Term Missions of Small Lunar Rovers Using an MLI Curtain System

open access: yesInternational Journal of Aerospace Engineering, 2019
This paper proposes a lunar night survival method for small rovers using an MLI (Multilayer Insulation) curtain system for long-term missions. Until recently, it was difficult to install RHU (Radioisotope Heating Units) or other temperature maintenance ...
