Balloons deformation experiment. a An evaluation status defined in this experiment. b The summary of the experimental results. c The balloon’s deformation under the cross area of 59%, the flow rate of main flow of 9.5 mL/s. (i) t = 0 s: inflow started. (ii) t = 7.6 s: the control flow 1 was stopped. (iii) t = 12 s: the balloon contracted. (iv) t’ = 0 s: inflow started. (v) t’ = 7.6 s: the control flow 2 was stopped. (vi) t’ = 14 s: the balloon contracted. d) The balloon’s deformation under the cross area of 59%, the flow rate of main flow of 10.8 mL/s. (i) t = 0 s: inflow started. (ii) t = 7.6 s: the control flow 1 was stopped. (iii) t = 20 s: the balloon contracted. (iv) t’ = 0 s: inflow started. (v) t’ = 7.6 s: the control flow 2 was stopped. (vi) t’ = 83 s: the balloon contracted
