Default Channel with 2D surface mounted obstacle

Posts: n/a
Dear all,

I am looking for (DNS/LES) simulations or experimental measurements of turbulent channel flow with a 2D surface mounted obstacle having rectangular section. I am interested in obstacle with height up to half of the channel height and Reynolds_bulk less than 8000/10000. Of course I am speaking of published references but any kind of indication will be gratefully appreciated.

Thank you in advance.

There are a magnitude of published results for experiment and quite a few predictions with turbulence models, feel free to contact me if you need any advice or additional references. The DNS and LES are however very few, below are something that might be helpful, although not entirely what you are looking for:

author = "M. Ciofalo and M. W. Collins",

title = "Large-eddy simulation of turbulent flow and heat transfer

in a plane and rib-roughened channel",

journal = "Int. J. for Numerical methods in Fluids",

volume = 15,

pages = "453-489",

year = 1992


author = "D. Laurence and S. Parneix and P. Durbin",

title = "Second Momentum Closure of a DNS Backstep Flow Database",

booktitle = "2nd Int. Symposium on Turbulence, Heat and Mass Transfer",

year = 1997

with reference to the DNS-data of Le, Moin and Kim


author = "A. Murata and S. Mochizuki",

title = "Large Eddy Simulation Applied to Internal Forced-Convection Cooling of Gas-Turbine Blades",

booktitle = "11th IHTC",

pages = "565-570",

year = 1998


You should of course also check surface-mounted cube simulations, although not in my area I could send you a copy of one of my colleagues (S. Krajnovic) forthcoming thesis (in a couple of weeks) treating LES of such flows.

Best Regards
