I'm having a little trouble setting up the case in OpenFOAM 1.7 using k-omega SST turbulence model.
What are I need to define (Boundary Condition) for k-omega turbulent model in OpenFoam so as model has to compare with Ansys-Fluent (k-omega standard turbulence model).
which solver I need to take in OpenFoam for compare with Ansys-Fluent (k-omega standard turbulence model).

You will have to decide if you want to run the model in low Reynolds number mode or in high Reynolds number mode. The difference is to have the first cell y+<1 or between 30 and 100. You can then use the following boundary conditions
for low Reynolds mode
k: all walls type fixedValue; value 1e-10; omega: all walls type omegaWallFunction; nut: all wall type nutLowReWallFunction;
k: all walls type kqRWallFunction; omega: all walls type omegaWallFunction; nut: all walls type nutkWallFunction;
