Webb1 feb. 2010 · A new experimental procedure to generate solitary waves in a flume using a piston type wave maker is derived from Rayleigh's (1876, [18]) solitary wave solution. Webb13 juni 2024 · The other concern of the present work is the modelling of irregular wave patterns using flap and piston type wave-makers. As a consequence of a survey procedure to find a compromise between computational time and the order of accuracy of the solutions, a peak frequency range of 0.50–0.80 [Hz] has been determined as a …

Webb1 maj 2016 · The focus of present study is on how to generate solitary waves in a wave flume using a piston type wave maker. Experimental observations are implemented to evaluate the stability of the generated solitary waves. A better “stability” implies that the generated solitary wave can travel a longer distance without an obvious decay. WebbPiston-type wave makers can also be installed as multiple devices arranged in a wave basin (e.g., Rhinefrank et al., 2010). Figure 27.3. Dam-break and piston mechanism for bore generation. In dam-break setups the bore is generated by suddenly opening a gate and the subsequent water release from an impounded storage (A).
