Numerical results for flow in a slit representative of an idealized in vitro tube containing a single AV cushion undergoing sheer conditions equivalent to those in an idealized stage 25 chick heart during systole. There is a centerline entrance velocity of 0.36 m s−1 corresponding to a Reynolds number of 760. An eddy is present on the outflow side of the cushion. (a) Streamlines resulting in a maximum velocity of 0.44 m s−1 over the cushions; (b) shear stress profile over the heart tube’s bottom arc length with a maximum shear stress on the cushion surface of 110 dyne cm−2; (c) ambient pressure profile with maximum and minimum pressure occurring at the front and back face of the cushion.
