Asymptotic expansions of the eigenvalues and norms for perturbations about the Falkner--Skan solution
Carlos Lozano, Jorge Ponsin
We derive large-mode asymptotic expansions for the eigenvalues and eigenfunction norms of the Chen-Libby perturbation problem about Falkner-Skan boundary-layer profiles. The analys…
Libby-Fox perturbations and the semi-analytic adjoint solution for laminar viscous flow along a flat plate
Carlos Lozano, Jorge Ponsin
The paper derives a semi‑analytic adjoint solution for the two‑dimensional laminar boundary layer on a flat plate using Libby‑Fox perturbation theory and Green’s functions, and app…
A variational formulation of the adjoint Kutta condition in potential flow
Carlos Lozano, Jorge Ponsin
We give a variational formulation of the continuous adjoint Kutta condition for two-dimensional subcritical potential flow, with emphasis on the Kutta condition and the role of the…
Properties of Adjoint Solutions of the Full-potential Equations for Two-Dimensional Subcritical Flow
Carlos Lozano, Jorge Ponsin
The adjoint full-potential equations are studied for two-dimensional (2D) steady subcritical flows. In contrast with the incompressible case, explicit closed-form solutions are gen…
Enhanced Wall Boundary Modeling for Turbulent Flows Using the Lattice Boltzmann Method with Adaptive Cartesian Grids
Jorge Ponsin, Carlos Lozano
We propose an enhanced wall-boundary treatment for the lattice Boltzmann method (LBM), designed for high-Reynolds-number turbulent flows on adaptively refined Cartesian grids. The…
Wall boundary conditions for Lattice Boltzmann simulations of turbulent flows with wall functions
Jorge Ponsin, Carlos Lozano
This paper investigates wall boundary condition schemes for the simulation of turbulent flows using the Lattice Boltzmann method (LBM) coupled to turbulence models with wall functi…
