Title: | A Second-order accurate lattice Boltzmann non-Newtonian flow model | Contributor(s): | Boyd, Joshua (author); Buick, James (author); Green, Simon (author) | Publication Date: | 2006 | DOI: | 10.1088/0305-4470/39/46/001 | Handle Link: | https://hdl.handle.net/1959.11/1642 | Abstract: | A second-order accurate lattice Boltzmann model is presented for non-Newtonian flow. The non-Newtonian nature of the flow is implemented using a power law model. This is used to enable the accuracy of the model to be assessed and is not a limitation of the model. The second-order accuracy is demonstrated for a range of power law model parameter values representing shear thinning and shear thickening fluids. These results are compared with those of Gabbanelli et. al. (2006 'Phys. Rev.' E 72 046312) and it is noted that a higher order of accuracy and greater computational efficiency are achieved. These results demonstrate the suitability of the LBM for shear-dependent non-Newtonian flow simulations. | Publication Type: | Journal Article | Source of Publication: | Journal of Physics A: Mathematical and General, v.39, p. 14241-14247 | Publisher: | Institute of Physics Publishing Ltd | Place of Publication: | United Kingdom | ISSN: | 1361-6447 0305-4470 1751-8121 1751-8113 |
