Abstract
Inflow-boundary based Navier-Stokes (NSE) wave tanks are prone to volume ad-
dition, especially whilst generating steep (H/λ > 0.03) waves in near-shallow water (kh
< 1). In the present work, a volume-preserving, inflow boundary based numerical tank is
proposed in the two-phase NSE framework. Volume effluxed under troughs is balanced
against that in- fluxed under crests using kinematic stretching. The wave tank is
tested for generation of steep (H/λ = 0.037, 0.048), trochoidal waves in near-shallow
water (kh ≈ 0.8). A comparison with baseline inflow formulation demonstrates that the
proposed inlet boundary effectively restricts volume addition without inducing wave
distortion. The NWT model is later implemented to wave-structure interaction occurring
during low frequency (T = 2 s) wave propagation over a
submerged trapezoidal bar. Good agreement with experimental data is reported.
