Analysis of a Tubular Torsionally Resonating Viscosity–Density Sensor

Abstract: This paper discusses a state-of-the-art inline tubular sensor that can measure the viscosity–density ( ρ η ) of a passing fluid. In this study, experiments and numerical modelling were performed to develop a deeper understanding of the tubular sensor. Experimental results were compared with an analytical model of the torsional resonator. Good agreement was found at low viscosities, although the numerical model deviated slightly at higher viscosities. The sensor was used to measure viscosities in … Show more

“…For rotating or torsional sensors, the balance of torques is considered. The fluid-induced torque is again a function of δ/R [148,149,[180][181][182][183]. The hydrodynamic function for torsional blades is reported, e.g.…”

“…For example, a study involving drop-weight-impact-test of composite clearly demonstrate this phenomenon [8,9]. The resonance phenomenon occurs if the natural frequency of the structural system matches with the frequency of dynamic loading, which may reveal system characteristics [10,11] and if not planned may lead to structure failure [12][13][14]. Tremendous efforts have been made to study the failure mechanism including use of novel techniques such as thermography [15][16][17].Access to computational power has supported the use of numerical methods for various complex multiphysics studies [18,19].…”
