velocity intialization of two approaching liquid drop collision in air medium (Fluent) ?

(OP)
how to intialize both droplets with initial velocities, one droplet velocity in positive x direction and another droplet in negative x direction in fluent solver. i defined the zones for each droplets seperately in the domain ,i patched the zones with initial velocity but while simulation the droplets are not moving. what frame of reference should i use, relative to cell zone or absolute?

please see the jpg file of my domain setup and i also attached .wbpj file ,please suggest improvements and corrections.
