Computational Fluid Dynamics Erosion Investigation Using Single Objective Adjoint Shape Optimization
Publication: Journal of Pipeline Systems Engineering and Practice
Volume 11, Issue 3
Abstract
Adjoint methods integrated with computational fluid dynamics (CFD) tools can be used to tackle geometric optimization in processes and equipment in an industrial environment. This work presents a workflow for geometric optimization on a typical pipe elbow geometry using an adjoint–CFD methodology. It uses the ANSYS Fluent CFD and discrete adjoint solver in a stepwise way to guide shape modification to decrease pipe pressure drop. Finally, it discusses the effect of the optimized shape configuration on the predictions of three well-known erosion models. For the majority of gas velocity conditions investigated, a decrease occurred in the peak values and area spread of the erosion spots for the shape-optimized geometry. For some of the velocity conditions investigated a new erosion spot was predicted for the optimized geometry.
