surface renewal model
A turbulent exchange model that assumes that fluid near a surface is intermittently replaced by well-mixed fluid from adjacent layers, thereby disrupting the viscous sublayer at the surface itself.
Near-surface gradients are assumed to be restored by conduction according to
where T is temperature and κ is thermal diffusivity.
