Wall-Modeled Large Eddy Simulation and Detached Eddy Simulation of Wall-Mounted Separated Flow via OpenFOAM

Round 1

Reviewer 1 Report

Dear Authors,

The paper seeks to establish robustness of various unsteady simulations under challenging conditions that entail flow separation.  In particular, WMLES, SST-DES and SA-DES  are used to study flow separation encountered by 

 

a) flow over cylinder

b) wall mounted hump 

c) transonic flow over an axisymmetric bump with shock induced separation.

 

 

 are studied with Openfoam simulations. 

 

 

The main finding is :

Under a coarser grid requirement only SA-DES is able to predict the location of separation for the case (b-c) while WMLES and SST-DES fail. 

 

 

Although the paper is well written and methodology is straightforward, it suffers from poor grammar and sentence structure. Furthermore, line plots are hardly visible and must be improved: (figures: 6, 9, 13 and 15 )

 

 

 

Nevertheless, the article is well written, and will be of interest to the openfoam community. Although the scope is limited, I am still inclined to give authors a chance for revision and future publication.
