A water model is studied to simulate physical phenomena in the Lintz-Donawitz (LD) steel converter. The depression in the liquid, due to the impinging gas jet, is measured by means of a video camera. Image processing tools together with a non-linear mathematical model based on the physics of the liquid-gas system are used to describe the cavity profile. Under the assumption that the cavity profile is stationary, a quantification of the uncertainty of the depth and diameter estimates is given. The variance of the estimates is experimentally shown to decrease by 50% under the assumption that the cavity depth and diameter oscillations can be described as a sum of a small number of sine waves.
