Restrict the particles system, Even when the gameobject is rotating .

Hi All,

 I am newbie to particle system in Unity. Currently i am working on latest particles 

system to get the basic air effect. These particles are stable and flowing as my need.

Now the problem is: As when i move/rotate the parent gameobject, The particles are splitting for a movement.

Kindly check the below images:

1) Without Movement/Rotation:

2)With Movement/Rotation:

 In 2nd case they are exploring and taking few seconds to get the correct effect.

Kindly help me to fix the particles exploring effect(Moving out off the pipe) while move/Rotation of the Object.

Advance Thanks...
