    "abstract": "We report experimental results for the Kelvin-Helmholtz instability between\ntwo immiscible fluids in parallel flow in a Hele-Shaw cell. We focus our\ninterest on the influence of the gap size between the walls on the instability\ncharacteristics. Experimental results show that the instability threshold, the\ncritical wavelength, the phase velocity and the spatial growth rate depend on\nthis gap size. These results are compared to both the previous two-dimensional\nanalysis of Gondret and Rabaud (1997) and the three-dimensional analysis\nrecently derived by Plourabou=E9 and Hinch (2001), showing that the agreement\nis still not complete especially when gap size increases.",
