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…
Efficient solutions of eigenvalue problems in rarefied gas flows
Lei Wu
The linear stability analysis of the Boltzmann kinetic equation has recently garnered research interest due to its potential applications in space exploration, where rarefaction ef…
