Abstract:	Peristaltic pumps play an indispensable role in transporting sensitive fluids, especially at low flow rates down to the milliliter per hour range. Considering complex and variable tube setups including various fluid dynamically active components, the calibration of these pumps poses significant challenges due to the intricate contributions of the components to pressure loss. This study addresses the challenge posed by the potentially innumerable setup combinations that could emerge in practical applications. Recognizing the impracticality of empirical calibration measurements for each possible setup and process condition, our team pursued the development and validation of a numerical modelling approach. Given the importance of efficiency in practical applications, we diligently assessed the computational demand and efficiency of the numerical strategy. Initially, a 3D fluid-structure interaction (FSI) approach for multiphysics modelling was adopted. However, recognizing the excessive complexity and computational load, the strategy was streamlined to a more simplified yet effective methodology, relying on geometric displacement of the liquid due to the tube deformation within the peristalsis of the pump. Besides the viscoelastic behavior of the tube material, the characterization of the pressure loss behavior of each individual fluid dynamic component within the tube system was crucial. We undertook a series of rigorous fluid dynamic experiments to conduct these characteristics. The findings from these experiments were subsequently integrated into the solver development phase. The final solver showcased reliable performance. We validated its efficacy through a series of tests, and it demonstrated consistent and accurate predictions. We are pleased to announce that this novel solver offers an innovative approach for calibrating peristaltic pump systems encompassing complex setups and varying process conditions.
