Title: | Pressure losses and limiting Reynolds number for non-Newtonian fluids in short square-edged orifice plates | Authors: | Ntamba-Ntamba, BM Fester, Veruscha G |
Keywords: | Pressure Losses;Reynolds numbers;Non-Newtonian Fluids;Short square-edged orifice plates | Issue Date: | 2012 | Publisher: | Journal of Fluids Engineering | Source: | Journal of Fluids Engineering-Transactions of the ASME, 134:091204-1-091204-9, 2012 | Abstract: | Correlations predicting the pressure loss coefficient along with the laminar, transitional, and turbulent limiting Reynolds numbers with the β ratio are presented for short square-edged orifice plates. The knowledge of pressure losses across orifices is a very important industrial problem while predicting pressure losses in piping systems. Similarly, it is important to define stable operating regions for the application of a short orifice at lower Reynolds numbers. This work experimentally determined pressure loss coefficients for square-edged orifices for orifice-to-diameter ratios of ββ = 0.2, 0.3, 0.57, and 0.7 for Newtonian and non-Newtonian fluids in both laminar and turbulent flow regimes. | URI: | http://dx.doi.org/10.1115/1.4007156 http://hdl.handle.net/11189/5689 |
