Validation of 3D-Scanned Models for Aerodynamic Analysis and Real-Time Flow Visualisation

Abstract

This thesis presents the validation of 3D-scanned models for aerodynamic analysis and the real-time visualisation of airflow using ProCap system. Two main aspects are addressed regarding the validation of the 3D-scanned models. First, the visualisation performance within the ProCap software is evaluated, including the necessary steps for importing the model into the system. Second, a deviation analysis is conducted to assess whether the aerodynamic body—in this case, a GTA aeroplane model—meets the required tolerances, which are critical for ensuring a good aerodynamic performance. Additionally, the need to recreate the scanned surface is discussed, although without a specific practical case. Concerning the ProCap system, this thesis explores its setup, its advantages and disadvantages, and its potential for aerodynamic studies. More precisely, two studies are carried out to observe the effects of varying the angle of attack: first on an aerofoil model and the second on a GTA aeroplane model. All of the above is supported by the relevant theoretical foundations.
