A mesh adaptation strategy for complex wall-modeled turbomachinery LES

نویسندگان

چکیده

A mesh adaptation methodology for wall-modeled turbomachinery Large Eddy Simulation (LES) is proposed, simultaneously taking into account two quantities of interest: the average kinetic energy dissipation rate and normalized wall distance y+. This strategy first tested on a highly loaded transonic blade with separated flow, compared to wall-resolved LES results, as well experimental data. The allows predict fairly boundary layer transition suction side recirculation bubble pressure side. method then real turbofan stage which it shown that general operating point computation converges toward one. Furthermore, comparison turbulence predictions hot-wire anemometry show good agreement soon performed, confirms efficiency proposed method.

Multiblock Structured Mesh Generation for Turbomachinery Flows

Multiblock structured meshes offer better computational efficiency than the unstructured meshes which, on the other hand, are more flexible for complex geometries. The multiblock structured meshing could be more useful if the partitioning of the domain can be performed automatically. In this paper, we consider various automated blocking approaches for some turbomachinery zones. We then assess t...

DNS , LES , and wall - modeled LES of separating flow over periodic hills

Separating flow in a channel with streamwise periodic constrictions is investigated using direct numerical simulation (DNS), large eddy simulation (LES), and wall-modeled LES (WMLES). The Reynolds number based on the hill height and the bulk velocity above the hill crest is 10,595. The results presented include mean velocities, Reynolds stresses, and separation/reattachment points. High-resolut...

Abstract: P4HB: The Ideal Mesh for Complex Abdominal Wall Reconstruction?

While a plethora of techniques are available for ventral hernia repair (VHR), these may fall short in the face of chronic near-total loss of abdominal domain. The Wittmann patch (Star Surgical, Burlington, WI) has been described in the literature as an acute method of maintaining abdominal wall integrity with planned re-laparotomy. However, we demonstrate that it is also an effective adjunct to...
