Ray effect in rarefied flow simulation [PDF]
Journal of Computational Physics, 2020 Ray effect usually appears in the radiative transfer when using discrete ordinates method (DOM) in the simulations. The cause and remedy for the ray effect have been intensively investigated in the radiation community. For rarefied gas flow, the ray effect is also associated with the discrete velocity method (DVM).

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

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