摘要:

A new method for facilitating the transport of very viscous materials through lubrication of the inside wall of pipes was studied in model inclined plane and pipe geometries using 26 and 38% tomato paste as examples of very viscous suspensions and carboxymethyl cellulose dispersions as model lubricants. It was shown that a high apparent yield stress was necessary and that 17 to 53‐fold increases in flow rates in pipe flow at pressure drops ∼10.0 psi were obtained. Experimental flow times using an inclined plane and flow rates in pipe flow geometries were predicted in a mathematical analysis. An impact loading squeezing flow analysis was used in the case of inclined plane experiments; plug flow of tomato paste surrounded by a thin film of lubricant was assumed in the case of pipe flow. For inclined plane experiments the correlation coefficient was 0.98 and for pipe flow the correlation coefficient was 0.88 signifying reasonably good agreement between predictions of models and the results obtained from the experiments.
