The application of the authors' method used the stability parameter (i. e. Eq.(1)) for predicting the lower critical Reynolds number is extended to include the flow of Herschel-Bulkley fluids in pipes and between parallel plates.
The theoretical equations for calculations of the lower critical Reynolds number for the Herschel-Bulkley fluids flow in pipes and between parallel plates were derived as Eqs.(10) and (22) respectively These equations are not confirmed byexperimental data but would appear suitable for the prediction of the lower critical Reynolds number, since the theoretical results used the authors' method for the flow of pseudo-plastic fluids and Bingham plastic fluids, which may be regarded as a special case of Herschel-Bulkley fluids, in pipes and between parallel plates showed good agreement with the experimental results.
