Experimental results from a combined wind–wave tank are presented. Wind profiles and resulting wind–wave spectra are described, and an investigation of the airflow above breaking waves is presented. Monochromatic waves created by the wave maker are directed towards a submerged topography. This causes the waves to break at a predictable location, facilitating particle-image-velocimetry measurements of the airflow above steep breaking and non-breaking waves. We analyze how the breaking state modifies the airflow structure, and in particular the extent of the sheltered area on the leeward side of the waves. Results illustrate that while the geometrical properties of the waves greatly influence the airflow structure on the leeward side of the waves, the state of breaking (i.e., whether the waves are currently in a state of active breaking) is not observed to have a clear effect on the extent of the separated flow region, or on the velocity distribution within the sheltered region.

介绍了组合式风浪水箱的实验结果。描述了风廓线和由此产生的风波谱，并介绍了对破碎波上方的气流的研究。造波器产生的单色波指向淹没的地形。这会导致波在可预测的位置破裂，从而有助于对陡峭的破裂波和非破裂波上方的气流进行粒子图像测速测量。我们分析了破碎状态如何改变气流结构，特别是波浪背风侧的遮蔽区域的范围。结果表明，虽然波浪的几何特性极大地影响了波浪背风侧的气流结构，但破碎状态（即，
