Two-dimensional flow field Cloud map. Note: Numerical simulation illustrated the calculated results of Liquid flow direction (white arrow),flow velocity, coupling surface pressure and tube wall shape variables at two time steps (0.38, 1.12 s), The former (a) represents fluid is squeezed out when the sphincter is contracted, the latter (b) represents fluid is inhaled when the sphincter relaxes.
