One the Greatest project which we face on , is gas station CFD Simulation , at this project  we wrote numerical code in EES ( Engineering Equation solving ) For find and approve fluid characters  in Pipe / leak point and  Station Ambient .

we use Autodesk CFD for check fluid sweep direction  in station space for finding critical Location of station that amount of Gas  LEL is suitable for happen a terrible  event .

all of results was good  till 2 phase fluid behavior seen in fluid actions , and finally we modificating boundary conditions and set relevant data accordance with 2 phasse fluid  law and reach a primary solution .
