Title
A Water Model Study on the Recirculation Flow Characteristic in Ladle Injection Metallurgy
최성조S . J . Choi, 윤종규J . K . Yoon
Abstract
Experimental and theoretical studies were made in order to discuss the characteristics of recirculating flow in the ladle injection refining process. A mathematical prediction for the recirculating flow rate of liquid in a gas stirred ladle is developed on the basis of the turbulent clavier-Stokes equation using the k-ε model and momentum balance. Mean residence time of a tracer particle is measured in order to evaluate the recirculating flow rate of the liquid in the water model. The calculated valve of the recirculating flow rate is well agreed with the experimental result in the water model. The volumetric entrainment ratio is found to be very large with a magnitude of 30-120 under a normal stirring condition.
