0 - Publications, reports from the project:

1 - Objectives

1.1 Four wave interactions?

Get statistics to converge 4 waves correlations

1.2 Breaking waves?

Larger amplitude to get breaking waves

1.3 Inverse cascade?

Force at larger frequency to let space to develop an inverse cascade

1.4 Two layers

2 - Experimental setup

2.1 - Forcing

Motors: 1V = 5Hz

2 reductors: x20, x10

Cams: 10 to 50 mm of amplitude

TODO:

  • Add drawings

Positions of wave makers:

Wavemaker 1: x= -3.14m, y = 3.22m, angle with axis x = 10.3°

Wavemaker 2: x= 3.51m, y = -3.09m, angle with axis x = -9.6°

2.3 - Measurements
