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…
