1. Proposed Project Title. The project title should not be general. It should be concise and

informative (10%) To analyse the fluid dynamics and observe the hydrodynamic performance of a submarine as it performs 3 simple missions.

Is the proposed project relevant to your final year project? If yes, what is the title of your final year project?The submarine is a final year project for Group 1458: Design and Build of a Submarine – Mission Demonstration.

2. Please describe the project background and engineering problems of the project (up to 5 sentences, and 1-2 figures or drawings if possible). (15%)The autonomous underwater submarine has been designed and built from previous students in the past 2 years. The submarine will undergo subsystem testing, as well as an upgrade to its mission programming codes and dynamic control algorithms. Once the subsystems are fully integrated, full scale testing will commence where the submarine will attempt 3 simple missions in a controlled environment (potentially a clear swimming pool). Virtual modelling of the submarine will provide great detail of the submarine’s hydrodynamic performance.

3. Project Objectives, Flow variables and Proposed Possible Solutions.The overall objective of the project is to virtually model the submarine of our final year design project in order to investigate and determine several parameters. Three simple mission demonstrations have been planned that the submarine will perform. Through CFD we will endeavour to evaluate the hydrodynamic performance of the submarine as it operates these 3 simple missions. The submarine can travel at varying speeds of up to 4 m/s and dive to depths of up to 40 metres. Therefore, the main flow variable will be the flow of the water at different speeds and pressures in order to analyse the effect on the performance of the submarine. Possible solutions of pressures, stresses and forces acting on the submarine will be calculated in order to analyse the virtual performance of the submarine whilst undertaking the defined simple missions. Through this we hope to evaluate that the missions defined are practical and can be carried out successfully.4. Please briefly describe the progress so far, any problems encountered in the project, and if they were solved or not. Please give details of numerical models and solver setting such as turbulence model, convergence criteria, heat transfer model or multiphase model if it is used. (30%)

5. If possible, include one plot showing the geometry of your project, one showing the surface mesh and at least one showing preliminary results. (20%)
