See attachment for complete details Assignment brief You are required to use the computational fluid dynamics (CFD) package ANSYS to investigate secondary losses in pipes. More specifically, you will investigate the loss resulting from a single type of fitting, for example a sudden inline contraction or expansion, or a bend. The choice is yours, although it is recommended you choose a pipe fitting analysed in the Level 1 module EAT106 [1]. As part of the investigation you should attempt to correlate the results of your chosen scenario using ANSYS with those obtained by hand calculation, using the theory covered in EAT106. Submission Requirements You will hand in a report, which should include the following information: ? A specification of the problem you are investigating. This should include details of pipe dimensions, fluid used (water is the obvious choice), type of pipe fitting to be considered etc. ? A hand calculation, based upon the theory described in [1]. ? A table summarising boundary conditions and constraints. ? A description and rationale of the mesh size chosen, and a screenshot showing the mesh. ? Screenshots of the contour and vector plots produced by ANSYS. ? A comparison of the results obtained from ANSYS with those obtained by hand calculation, including a critical interpretation of the ANSYS graphical results.
