Application of continuous adjoint method to steady-state two-phase flow simulations

Annals of Nuclear Energy, 2018
Abstract Verification, validation and uncertainty quantification (VVUQ) have become a common practice in thermal-hydraulics analysis. An important step in the uncertainty analysis is the sensitivity analysis of various uncertainty input parameters. The common approach for computing the sensitivities, e.g.

Comparison of Continuous and Discrete Adjoint Methods for Topology Optimization in Structural Dynamics

Semi-analytic adjoint methods can be seen as breakthrough for deterministic topology optimization in structural dynamics since such methods have reduced the computational costs. Nevertheless, the costs are still very high, so that further improvements are crucial.

Aerodynamic Optimization of Car Shapes Using the Continuous Adjoint Method and an RBF Morpher

2018
This paper presents the application of the continuous adjoint method, programmed in OpenFOAM\(^{\copyright }\), combined with an RBF-based morpher to the aerodynamic optimization of a generic car model. The continuous adjoint method produces accurate sensitivities by utilizing the full differentiation of the Spalart–Allmaras turbulence model, based on ...
