SINOPSIS

The determination of optimal designs is an important objective in many engineering applications, including in convective heat transfer aera. This communication aims to present a topology optimization method for thermal flow problems. The cost function gradient is computed via an adjoint-state method. As the problem is solved with the Lattice Boltzmann Method, the adjoint-state equations are computed using a similar strategy than for LBM and are called Adjoint Lattice Boltzmann Equations (ALBE). This method is validated with a 2d thermal flow topology optimization problem with the objective of the mean temperature minimization subject to a pressure drop constraint.
