“…6). A similar observation was reported by Mazumdar et al (2014) in the case of hydrocyclone running with water only. This may be because for a given operating and design variable, feed volumetric flow rate directly depends on feed inlet pressure and hence at a given cross-sectional feed area increases the feed inlet velocity with inlet pressure, ultimately increasing the Reynolds number.…”

“…The spray angle was measured from captured image based on edge detection technique using image processing algorithm developed on the MATLAB™ platform. The detail methodology of the image reconstruction and post-processing techniques has been reported elsewhere (Mazumdar et al, 2014), however, a brief overview is given in the next sub-section.…”

“…An image processing based algorithm on MATLAB™ platform to quantify the discharge profile in terms of spray angle in a 2-inch Tega hydrocyclone running with water only was demonstrated by Mazumdar et al (2014). It was established that spray angle is stable and reproducible at a given operating condition to be used as an indicator for performance monitoring and control.…”

“…In view of the above, a systematical analysis of underflow spray angle as a performance monitoring tool in case of hydrocyclone running with slurry is investigated. Hence, an attempt has been made in the theoretical understanding of the hydrodynamics of spray formation and to confirm adaptability of the algorithm as described by Mazumdar et al (2014) in the case of hydrocyclone running with slurry. The image processing based technique was then adopted to measure the underflow discharge angle of a hydrocyclone treating various concentrations of fine silica slurries.…”

The performance of a hydrocyclone as a separation device is never perfect and rigorous research efforts are still continuing along various directions towards achieving optimum solutions. The modus operandi of performance optimization is important for quick and non-invasive monitoring of hydrocyclone performance. Therefore, in the present study, an application potential of spray angle as a performance monitoring tool has been explored to investigate the operation state of a hydrocyclone. In this context, phenomenological features of spray discharge over a wide range of injection pressure and feed solid concentration have been investigated. The emphasis of the present study is to verse the amendment of the hydrocyclone operational state with the corresponding change in underflow discharge pattern. The pattern of the underflow discharge profile was captured using a digital camera and analyzed based on an image processing algorithm to detect the discharge angle under different operating and design conditions. Stability and reproducibility of the spray angle at fixed operating condition have also been confirmed. Subsequent analysis shows that the spray angle is sensitive to variations of operating and design variables. More specifically the effect of feed slurry concentration has been characterized and is of major importance for the transition to roping. On this basis, an attempt has also been made to develop an empirical correlation based on experimental data. The developed correlation shows that the discharge angle could possibly be used as a reliable tool to monitor hydrocyclone performance.
