| Summary: | A mathematical and experimental investigation was made of the flow through porous media of non-Newtonian fluids with yield stresses. The analysis of the problem was made in three parts: 1) Two models were developed to describe the flow through porous media of a power-law fluid with yield stress, la) Darcy's law was modified by coupling the Herschel-Bulkley rheological model with the capillary flow model and hydraulic gradient description of a porous medium to generate a generalized form of the flow equation as: [See Thesis for Chemical Diagrams] 2a) An oil which exhibited a rheological behaviour which was well described by the Herschel-Bulkley model was developed by adding paraffin wax to Newtonian oils. Two oils were used, Clarus-B and Clarus-C oils supplied by Shell Canada Company, with 2.5%, 4% and 5% paraffin wax for the preliminary tests. Crude oil from the Peace River field in Alberta was also found to exhibit the same behaviour. 2b) The flow characteristics of the test oils and the crude oil were ... |
