An efficient treatment of heat-flux boundary conditions in GSIS for rarefied gas flows
Yanbing Zhang, Ruifeng Yuan, Liyan Luo +1
Heat-flux boundary conditions are challenging to implement efficiently in rarefied gas flow simulations because the wall-reflected gas temperature and density must be determined dy…
Surrogate-assisted airfoil optimization in rarefied gas flows
Xiaoda Li, Ruifeng Yuan, Yanbing Zhang +1
With growing interest in space exploration, optimized airfoil design has become increasingly important. However, airfoil design in rarefied gas flows remains underexplored because…
A fast-converging and asymptotic-preserving method for adjoint shape optimization of rarefied gas flows
Yanbing Zhang, Ruifeng Yuan, Lei Wu
Adjoint based shape optimization is a powerful technique in fluid-dynamics optimization, capable of identifying an optimal shape within only dozens of design iterations. However, w…
Wetted-Area Minimum and Inlet-Outlet Reciprocity in Optimal Manifolds of Rarefied Gas Flows
Ruifeng Yuan, Lei Wu
While flow optimization has been extensively studied in the continuum regime, its extension to rarefied gas flows remains less explored. Here, based on the Boltzmann model equation…
Adjoint shape optimization from the continuum to free-molecular gas flows
Ruifeng Yuan, Lei Wu
An adjoint-based shape optimization method for solid bodies subjected to both rarefied and continuum gas flows is proposed. The gas-kinetic BGK equation with the diffuse-reflection…
Efficient parallel solver for rarefied gas flow using GSIS
Yanbing Zhang, Jianan Zeng, Ruifeng Yuan +3
Recently, the general synthetic iterative scheme (GSIS) has been proposed to find the steady-state solution of the Boltzmann equation in the whole range of gas rarefaction, where i…
Capturing the influence of intermolecular potential in rarefied gas flows by a kinetic model with velocity-dependent collision frequency
Yuan RuiFeng, Wu Lei
A kinetic model called the -model is proposed to replace the complicated Boltzmann collision operator in the simulation of rarefied flows of monatomic gas. The model follows the…
