|Abstract:||Peristaltic pump technology is widely used wherever relatively low, highly-accurately dosed volumetric flow rates are required and where fluid contamination must be excluded. Thus, typical fields of application include food, pharmaceutical, medical technology and analytics. In certain cases, when applied in conjunction with polymer-based tubing material, supplied peristaltic flow rates are reported to deviate from expected set flow rates relevantly. Said deviations are related to i) chosen tube material, ii) total over all time of the pump cycles exerted on applied polymer tubes and iii) applied frequency of pump revolutions. This work presents a fast, dynamic, 2D Multiphysics simulation method, which significantly reduces the considered deviations by serving as the basis for elaborating an a priori operational setpoint correction. The numerical solver encompasses laminar fluid dynamics, geometric restrictions provided by peristaltic pump operation, as well as viscoelastic tube material properties and tube material fatigue effects. Within this work, a considerable variety of validation experiments and application examples of the novel methodology will be presented.|
