Study for the computational resolution of conservation equations of mass, momentum and energy. Preliminary analysis of turbulent flows

The present bachelor’s final thesis consists of a study for the resolution based on computational numerical methods of several problems related to the fluid mechanics and heat transfer field. The main objective of the study is to introduce the author to Computational Fluid Dynamics (CFD), allowing him to achieve advanced knowledge in numerical methods. Therefore, for this purpose, the project is based on the implementation and development of software, using C++ language, able to solve the different proposed problems considering its particularities. As can be seen throughout the document, the cases chosen are basically benchmark problems widely studied in order to be able to compare and verify the efficiency and accuracy of the solutions reached. In addition, the complexity of the studied problems increases throughout the project to assure the proper attainment of the objectives. The thesis is largely focused on the resolution of the mass, momentum, and energy conservation equation, also known as Navier-Stokes equations, for incompressible and laminar flows. Lastly, an introduction to the study of the turbulence phenomena is included, based on the analysis of preliminary cases.
