...Maokun Ye; Hamn-Ching Chen; Arjen Koop _ In this study, we perform CFD simulations for the NTNU Blind Test 2 experiment, in which two turbines were placed in a closed-loop wind tunnel and operating in line. The Reynolds-averaged Navier Stokes (RANS) equations with the k -ω SST turbulence model...

... in the air. In particular, the research activities seem to be concentrated in the 1970s and 1980s because large crane vessels were needed for marine construction. For example, the Japan Workvessel Association conducted model experiments for large crane barges. Although useful experimental data were obtained...

... and parapets in wave overtopping through abundant experimental data collected in the wave ume of the Leichtwei -Institute. Nevertheless, they pointed out that their existences may increase the wave loadings on the vertical wall. Ravindar et al. (2019) conducted large-scale (1:1) experiments to characterize...

... the full-scale case study (Fig. 4) is slightly different. At a location close to the seawall (i.e., Dw/d = 1 9512) (Fig. 4a), the experimental result shows a similar wave pattern as what has been observed in the scaled experiment; however, the corresponding numerical results do not show a clear double...

... scale. EXPERIMENTAL DETAILS The experiments involve a train of regular waves generated by a piston-type wavemaker (WM). The waves shoal over a 1:10 sloping beach and interact with a seawall af xed with a 90 recurved parapet. Two different sets of experiments have been carried out: (1) at model scale (1...

The variations of the pressure against time demonstrate the slamming characteristic of the vertical seawall at different locations. The impact pressure reaches the peak value immediately. According to the experimental and numerical simulation...

Numerical results are compared with experimental data regarding both free surface elevation and pressure on the wall. In general, a correct agreement between numerical predictions and experiments is obtained...

Experimental Design In addition to the single-factor experiment, the full-factorial design (FFD) method is used to design the experiment. In the present research, the cases for studying the effects of two factors (AR and RC) with the respective ve...
