Thermal Conductivity and Heat Transfer Coefficient of Concrete郭利霞North China University of Water Resources and Electric Power摘 要:A very simple model.... The heat transfer coefficient was determined by inverse analysis using the temperature measurements. From experimental results, it is noted that heat transfer coefficient increases with the increase......
; Change of activity coefficient with basicity (a) and V2O3 content (b) 由图3(a)可得,随着终渣碱度从0.35升高至1.28,渣中V2O3活度因子逐渐增加,从2.126增加至2.207,而铁液中V活度因子则呈现降低趋势,从0.031降低至0.027,由于系统活度因子γsys与呈正相关,而与fV2呈负相关,故随着碱度的增加,γsys逐渐... increase as the basicity of final slags increase and decrease as the V2O3 content increase. Based on the thermodynamic activity factor models, the variation of basicity and vanadium content of final slags......
