Hi Foamers,
I am doing spray simulation using interFoam solver. My inlet velocity BC's is based on cylindricalVelocityInlet .
PHP Code:

PHP Code:

boundaryField 
  { 
      INLET 
      { 
          type              cylindricalInletVelocity; 
          axis               (1 0 0); 
          origin             (-0.0055 0 0); 
          axialVelocity    constant 71.646; 
          radialVelocity   constant 30.412; 
          rpm                constant 0; 
          value               uniform (0 0 0); 
     } 


how can i add oscillating component of velocity i.e 5% of mean velocity to the above mentioned boundary condition.so i need to induce some amount of perturbation

Thanks in advance,
Vivek

Hi, Do you get any solution?
