Summary:To visualize the state of a molten steel in a mold of a continuous casting facility.SOLUTION: A visualization device 100 gives the first probability density function p(x|y) of a state vector xat a time t and the likelihood function L(x|y) of the state vector Xat the time t to the algorithm of a filter in which data assimilation is performed to derive the second probability density function p(x|y) of the state vector Xat the time t. The visualization device 100 derives the mode of the second probability density function p(x|y) as the estimate of the state vector xat the time t. Further, the visualization device 100 plurally derive the parameters of the temperate, flow velocity and boundary conditions of a molten metal 3 for obtaining numeric value analysis data Xat a time t+Δt based on the second probability density function p(x|y).SELECTED DRAWING: Figure 1 【課題】 連続鋳造設備の鋳型内の溶鋼の状態を可視化する。【解決手段】 可視化装置100は、時刻tでの状態ベクトルxtの第1の確率密度関数p(xt|y0:t-Δt)と、当該時刻tでの状態ベクトルxtの尤度関数L(xt|yt)とを、データ同化を行うフィルタのアルゴリズムに与えることにより、時刻tでの状態ベクトルxtの第2の確率密度関数p(xt|y0:t)を導出する。可視化装置100は、この第2の確率密度関数p(xt|y0:t)の最頻値を、時刻tでの状態ベクトルxtの推定値として導出する。また、可視化装置100は、この第2の確率密度関数p(xt|y0:t)に基づいて、時刻t+Δtでの数値解析データxtを求めるための溶鋼3の温度および流速、並びに境界条件のパラメータを複数導出する。【選択図】 図1
