HEAT TRANSFER UNDER SOLIDIFICATION OF LIQUID ON AGITATED VESSEL WALL

[摘要] References(8)The heat transfer under solidification of lauric and capric acids on the cooling wall of an agitated vessel is studied, and the over-all and convective heat transfer coefficients, respectively, are measured and correlated with the impeller Reynolds number. The over-all heat transfer coefficient decreases sharply as depositing solid layer forms, but the convective heat transfer coefficient is well correlated by the already reported correlation equation independently of existence of solid layer. That is, the convective heat transfer coefficient in the vessel with solid layer coincides with that in the vessel without solid layer.
