Abstract:	Batch heat transfer data was experimentally determined for two phase (solid—liquid) systems in a baffled agitated vessel. Three iron oxide and water and two kaolin and water suspensions were evaluated and were found to be pseudoplastic. A total of 231 heating and cooling data points were examined. Each suspension was evaluated using anchor, paddle, propeller and turbine impellers. Various sizes of the latter three impellers were used. The experimental heat transfer results for suspensions were compared with the Hagedorn and Salamone correlation for pseudoplastic liquids. Only partial agreement with the more dilute suspensions was obtained. Overall, the data for suspensions was shown to deviate as a function of weight percent solids. A dimensionless factor, weight percent liquid divided by weight percent solids, was evaluated which may be used to modify the above mentioned correlation and thus extend its usefullness to two phase systems.
