STUDY ON THE HEAT TRANSFER PROPERTIES OF BLACK LIQUOR FROM WHEAT PULPING

摘要

The heat transfer properties of black liquor from wheat pulp in a stirring apparatus were studied in this paper. By changing the experiment conditions of temperature-difference driving force, geometry shape and agitator speed, we investigated the heat transfer properties of black liquor from wheat pulp under the conditions of different physical properties,rheological properties, fluid power conditions and the space geometrical characteristics of fluid flow.Furthermore the related mathematical models and evaluation criteria based on the conventional methods and artificial neural networks were established. The experimental results showed that the above-mentioned factors have obvious effect to black liquor from wheat pulp.
