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…
Analytic adjoint solution for incompressible potential flows
Carlos Lozano, Jorge Ponsin
We obtain the analytic adjoint solution for two-dimensional (2D) incompressible potential flow for a cost function measuring aerodynamic force using the connection of the adjoint a…
On the characteristic structure of the adjoint Euler equations and the analytic adjoint solution of supersonic inviscid flows
Carlos Lozano, Jorge Ponsin
The characteristic structure of the two-dimensional adjoint Euler equations is examined. The behavior is similar to that of the original Euler equations, but with the information t…
