Abstract

This thesis documents a new approach to assess the aerodynamics of complex fluid dynamic systems using modern assessment methods associated with computational fluid dynamics (CFD). The method is developed to extract novel and additional insight in the context of a higher-fidelity modeling tool. Although the methods are based on classical control volume techniques balancing fluid momentum and energy, the approach uses the detailed data provided by CFD to expand on it. Classical methods typically use a fixing control volume defined at simple control surfaces, whereas this assessment method utilizes CFD to provide complex integrals on the control surfaces and uses this to evaluate multiple control volumes to track fluid momentum and energy. The approach refines the aerodynamic quantification and can dramatically expand upon a singular, convenient control volume. The benefit of the proposed methodology is demonstrated by tackling three challenges in aero and hydrodynamics from CFD. These problems include: 1) decoupling induced from profile drag on a wing in CFD, 2) identifying the aerodynamics contributions of a multiphase aerodynamic system, and 3) separating energy components of oscillating and heaving hydrofoils. Overall, the results from the new method indicated the validity of the method and novel quantification useful for aerodynamic designs.
