Definitions

  • the present invention relates to a new swell generator system, intended in particular for ocean engineering experimental basins.
  • beaters of the "flap" type which can be presented as a vertical flap driven by an alternative translational movement, or as an inclined flap, driven by an alternating tilting movement, said flap being able to -even be articulated and / or coupled to a device for translating its tilting axis (double-acting flaps).
  • beaters of the "plunger wedge” type constituted by a prism with a triangular section downwards, a large face of which slides in an alternating movement along the rear vertical wall of the channel.
  • the transfer function of these beaters is no longer very satisfactory and, moreover, these beaters are not adaptable to the case of very deep swell, swell and current pools.
  • the invention therefore relates to a wave generator constituted by a cylindrical float, mounted transversely in a basin, a short distance from the rear vertical wall of this basin, the generator of said cylinder having a substantially vertical rear part and a front part in the form of spout, this cylinder being associated with means imparting an alternative horizontal translation to it, the mean distance between the rear wall of said float and the rear wall of said basin being chosen so that a resonance phenomenon is created between the swell train caused by the oscillations of the water column between said walls and that created by the proper movement of the float, the superposition of these two trains giving rise to a very high transfer function in a selected interval of the swell period.
  • FIG. 1 it can be seen that, according to the invention, a cylindrical float 1 parallel to the vertical rear wall 2 of a swell pool, in a manner known per se, is animated, by means of a jack 3 of a so-called cavalry movement, that is to say of alternative horizontal translation.
  • FIG. 2 illustrates the influence, on the values of these transfer functions, of the distance from the rear of the mixer to the wall of the basin, that is to say the effects due to the phenomenon of resonance resulting from the cyclic variation of this distance.
  • the curves at VI correspond to different values of time average of the distance d, for a drummer conforming to that of Figure 1, having a width L at the waterline of 1.9 m, immersed by 1 m in a basin whose bottom 6 is 7 m and bottom 6 'is 3 m, the distance D being 10 m :
  • curves are to be compared to curve A, illustrating the variations in the transfer function obtained with a similar float, but driven by an oscillating movement around a transverse axis X.

1. System zur Erzeugung einer künstlichen Dünung in einem Versuchsbecken des ozeanischen Ingenieurwesens derjenigen Bauart, das eine von einem zylindrischen, zur Rückwand des Beckens parallelen Schwimmkörper gebildete Schlagvorrichtung enthält, dadurch gekennzeichnet, daß der Querschnitt des besagten Schwimmkörpers, d.h. die Erzeugende des besagten Zylinders, eine merkbar vertikale, d.h. merkbar zu der genannten Rückwand parallele Rückseite und eine Frontseite in Gestalt einer Schnauze aufweist und der besagte Schwimmkörper an mechanische Einrichtungen angeschlossen ist, die ihm eine abwechselnd horizontale Bewegung vermitteln, wobei der mittlere Abstand zwischen der Rückwand des besagten Schwimmkörpers sowie der Ruckwand des genannten Beckens derart gewählt wird, daß sich eine Resonanzerscheinung zwischen dem durch die Schwingungen der Wassersäule, die zwischen den genannten Wänden enthalten ist, und dem durch die eigentliche Bewegung des Schwimmkörpers erzeugten Schlagwellengang entwickelt, wobei die Überlagerung dieser beiden Wellengänge eine sehr gesteigerte Übertragungsfunktion in einem ausgewählten Intervall der Periode der Dünung verursacht.
2. System nach Anspruch 1, dadurch gekennzeichnet, daß zum Zweck einer Beschränkung des Kabbelns zwischen der Mauer und dem Schwimmkörper die hintere Fläche des Schwimmkörpers mit Bezug zur Vertikalen leicht zur Frontseite hin geneigt ist.
3. System nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, daß es in ein Dünungs- und Strömungsbecken eingebaut ist.
