Tidal inlets are part of the coastal sediment-sharing system, and an inlet will modify the nearshore and estuary morphology, as well as the up-drift and down-drift beaches. Morphologic response to an inlet varies over several time and spatial scales. This chapter discusses inlet morphology and related functional design considerations that must balance navigation and shoreprotection requirements...

Frequent inlet flow changes, especially in the same direction, typically cause problems for averaging level controllers. To obtain optimal flow filtering while being robust towards future inlet flow upsets closed loop robust MPC was used. Its performance and robustness is analyzed and compared to the optimal averaging level controller. The knowledge gained from the robust MPC exercise is also u...

The simultaneous removal of SO2/NO2 by limestone slurry was studied in a gas-liquid bubbling reactor. Experiments were carried out to find the effect of various operating parameters such as inlet concentration of SO2 and NO2, reaction temperature, O2 content in the flue gas and additive on the SO2 and NO2 removal efficiencies. SO2 removal efficiency decreased with inlet NO2 concentration, react...

A simple set of equations for bubbly flow through a vertical tube is rigorously derived by means of a scale analysis from the realistic equations posed by Pauchon. It is shown that under steady flow conditions the void fraction will relax from its value at the inlet towards an asymptotic value within only a short distance of the inlet. The relationship between the inlet void fraction and the im...

The effects of a typical glaze ice accretion shape on the performance of the M2129 S-duct inlet are computationally investigated for a range of flight Mach numbers. A Reynolds-Averaged Navier-Stokes (RANS) code with k-o> turbulence model is used to simulate the compressible viscous flow in the S-duct inlet. The glaze ice accretion on the cowl lip is modeled on a steady-state basis f rom N A S A...
