“…In addition, a SONOCHECK-ABD06 bubble meter (BM) is installed next to the pump discharge section to evaluate the air bubbles content inside the tested fluid. This non-invasive sensor is commonly employed for medical applications, e.g., to monitor the presence of bubbles during blood transfusions or dialysis by means of the ultrasound principle (Leung et al (2021)), or biotechnology processes (Roth et al (2016)). The ultrasound wave emitted by the device crosses the measuring section (pipe) and depending on the transit time to reach the receptacle, an analog output is produced.…”

Non-Newtonian fluids are involved in many industrial processes, e.g. in food and Oil&Gas applications. Since their viscosity varies with the imposed stress and rheology, pumping this type of fluids can lead to a considerable variation in the pump head, and overall efficiency is difficult-to-be-predicted. Since most manufacturers test their pumps only with water, selecting the appropriate pump to handle non-settling slurries may be challenging due to the non-linear effects, related to the fluid rheology and the critical interaction with the air bubbles. In this work, an experimental investigation was carried out on an on-purpose test bench, testing two mixtures of water and kaolin on a small centrifugal pump. The fluids were tested at two degrees of air bubbles content: an initial aerated condition and after a deaeration process. A critical analysis was conducted to relate the experimental pump performance variation with the air bubbles content.
