... are increased by the presence of the wall. This increase is most evident in the range of e/D values smaller than about 0.5. Both coefficients depend on the Reynolds number, Keulegan-Carpenter number, and the relative gap. The effect of the boundary layer or the penetration depth of the viscous wave is small...
