Numerical results for flow in a slit containing idealized stage 25 chick cushions with a thickness of 250 μm during diastole. The centerline entrance velocity is 0.2 m s−1 corresponding a Reynolds number of 71. Small eddies are present on the outflow side of each cushion. (a) Streamlines resulting in a maximum velocity of 0.39 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 277 dyne cm−2; (c) ambient pressure profile with maximum and minimum pressure occurring at the front and back face of the cushion.
