but.defenceThe student informed the examination committee about the methodology, results, and conclusions of his diploma thesis. He answered all questions posed by the reviewer. Prof. Petruška asked for clarification regarding the first reviewer’s question: What exactly does the symbol stand for? Does it represent the rotational speed of the arm or of the roller? Is there a connection between the two? The student attempted to explain, but his answer was rather unclear to the comittee. Doc. Charvát continued discussion on this topic. Doc. Lízal inquired about the criteria used for setting the time step in the simulations. The student explained his approach. In the subsequent discussion, Doc. Jan asked why the student had used much lower velocities than those applied in the real experiments. The student attempted to justify his assumptions, noting that the experiments had been conducted only after the model had been developed. However, he was not able to explain this sufficiently. Doc. Kalousek asked about the use of a 2D model, as well as the implications of applying a 3D model instead. The student replied that a 3D approach would require modifications in the code and, from the physical point of view, would introduce additional deformations and settings. His objective, however, was to develop a 2D model in order to compare CFD results with analytical solutions. A 3D model was envisaged as a subsequent step.cs

dc.description.abstractPeristaltic pumps (PP) play a critical role in various clinical applications such as dialysis, cardiopulmonary bypass, and extracorporeal membrane oxygenation, offering reduced haemolysis rates and fewer complications compared to centrifugal pumps. This study presents a comparative analysis of two advanced -computational fluid dynamics (CFD) methodologies for simulating the operation of peristaltic pumps (PP) in ANSYS Fluent. The study aims to identify the computational efficiency, accuracy, and physiological relevance of each approach by developing transient CFD models with appropriate boundary conditions. The goal is to support informed decision-making in selecting the most appropriate modelling strategy for high-fidelity simulations.en
