Main Results:

  • Identified transient and steady-state regimes in foam flow.
  • Developed and validated methods to correct for slip velocity.
  • Observed evolution of bubble size and arrangement with shear rate and time.

Conclusions:

  • A reliable foam rheological equation was determined.
  • The transient regime corresponds to foam's structural evolution.
  • Slip velocity was successfully evidenced and measured.
