I'm looking for the airfoil characteristics for SAND 0018/50 (SANDIA 0018/50) that is used wind turbine (VAWT of Darrieus type) tabulated for different Angle of attack and Reynold number?
Any suggestions are highly welcome.

You may also use the open source programme QBLADE: http://www.q-blade.org/#downloads . The software is ok also for VAWT. And the software is not very complicated ... You may draw polar plots ( Clift, Cdrag, .. for different angle of attack and win speed (i.e. reynolds numbers)
Dear Amin,
I was also going to suggest you to use QBlade. QBlade is open source software for design and simulation of horizontal and vertical axis wind turbines (HAWT and VAWT), distributed under the GNU General Public License.
What is most interesting to you is that its integration in XFOIL allows airfoil design and airfoil performance analysis, and even allows also for extrapolation of airfoil performance data to 360° angle of attack, etc. That is, QBlade, using panel methods, allows obtaining for any given airfoil the lift and drag coefficients for different angles of attack and values of Re. You can download QBlade and manuals here: http://qblade.npage.de/
If the specific airfoil that you want to test is not available in QBlade's airfoil library/database, in the following UIUC's link you can find the airfoil coordinates to import to QBlade: http://m-selig.ae.illinois.edu/ads.html
Hope this is useful,
Jose
Thanks to all who contributed to this question.
I couldn't find detailed aerodynamics characteristics of SAND 0018/50 in the Sandia report (Tailored Airfoils for Vertical Axis Wind Turbines) link given by Gireesh Ramachandran neither its coordinates, only some details about SAND 0015/47.
I'm a bit familiar with Qblade where I couldn't find SAND 0018/50 airfoil there (https://sourceforge.net/p/qblade/discussion/1195932/thread/54cc827aab/?limit=25#a005) and I need import the aerodynamics data or at least the airfoil coordinates and analyze it in Qblade using XFoil as suggested by Jose Ignacio Rojas Gregorio
Also I was not able to find the airfoil coordinates neither here http://www.airfoiltools.com/search/airfoils?m=a
Nor https://m-selig.ae.illinois.edu/ads.html as suggested. Any further help?
The specif airfoil I'm looking for SAND 0018/50 was sketched in (https://digital.library.unt.edu/ark:/67531/metadc1197820/m2/1/high_res_d/6821919.pdf) as attached. However still I couldn't find it's coordinates tabulated for x and y. An help in the regard will be highly appreciated.
