Gas Jet Impinging on Liquid Surface: Cavity Shape Modelling and Video-based Estimation
نویسندگان
چکیده
A water model is studied to simulate physical phenomena in the 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 nonlinear mathematical model based on the physics of the liquid-gas system, are used to describe the cavity profile. The properties of the model are investigated. A quantification of the uncertainty of the cavity depth estimates is given and the frequency content of the oscillations of the indentation profile is characterized by using the Fast Fourier Transform.

Deformation of a liquid surface due to an impinging gas jet: A conformal mapping approach
A theoretical and experimental study is performed on the deformation of a free surface between two fluids in a gravitational field, due to a jet in the lighter fluid impinging at right angles to the surface. For the two-dimensional case, we present a mathematical model using the method of conformal mapping. The strength of our method lies in its general application to analytically study the int...
متن کاملParameter and State Estimation using Audio and Video Signals
The complexity of industrial systems and the mathematical models to describe them increases. In many cases point sensors are no longer sufficient to provide controllers and monitoring instruments with the information necessary for operation. The need for other types of information, such as audio and video, has grown. Suitable applications range in a broad spectrum from microelectromechanical sy...
متن کاملDynamics of Air-Blown Dimples
A classical problem in fluid mechanics is that of a jet impinging on a solid surface. During the 1960’s, partly driven by applications in the steel industry, the exploration of this field of study shifted towards the interaction between a gas jet and a deformable liquid surface (Figure 1), where often the shape of the deformation and its relation to the balance of forces were studied. This is a...
متن کاملEffect of Injection Parameters on Jet Array Impingement Heat Transfer
The purpose of the present study is to clarify the heat transfer characteristics with multiple jet impingement aiming at the highly efficient cooling performance. In the study, we investigated the effect of injection parameters on circular jet array impingement heat transfer. As we focus on interference among the adjacent impinging jets, tests are mainly conducted at the minimum crossflow condi...
متن کاملExperimental study and numerical simulation of three dimensional two phase impinging jet flow using anisotropic turbulence model
Hydrodynamic of a turbulent impinging jet on a flat plate has been studied experimentally and numerically. Experiments were conducted for the Reynolds number range of 72000 to 102000 and a fixed jet-to-plate dimensionless distance of H/d=3.5. Based on the experimental setup, a multi-phase numerical model was simulated to predict flow properties of impinging jets using two turbulent models. Mesh...
