ME7724 Computational Fluid Dynamics for Engineering

Module Learning Outcomes

The following module learning outcomes and professional body learning outcomes are tested in this assessment:

(LO1) Define and analyse engineering fluid flow problems using the Navier Stokes equations. Simplify flow problems and solve them exactly. (SM1m, SM2m, G1)
(LO2) Construct appropriate solid models for CFD analysis, setup the solution domain and generate suitable surface and volume grids via meshing tool. (SM3m, SM5m)
(LO3) Understand both flow physics and mathematical properties of governing

Navier-Stokes equations and define appropriate boundary conditions. (EA3m)

The aims of this individual assignment are twofold:

(1) to investigate the analytical solution derived from Navier-Stokes (NS) equations through simplification process
(2) to construct mesh over typical curved geometry models, reflecting known physical flow features of near wall viscous layer and run simple CFD simulations Submission details and requirements:

(1) You need to submit an electronic copy of the report in PDF format to Canvas/ME7724 for similarity and plagiarism checks. Please avoid MS Word file submission on Canvas because of some formatting issues with equations. Your work should be first fully word-processed (not handwritten and scanned) and then a copy saved as PDF for Canvas submission. Hardcopy not required. Do not include ANSYS WB files to the Canvas Submission.

(2) You need to upload an archived copy of your ANSYS WB files (.wbpz file) for Question 2 on Box and include the link in an appendix e.g. appendix A in your report.
(3) The maximum page limit for the report to be submitted on Canvas is 30 pages A4, single space (for the whole assignment). No other specific format is imposed.
(4) You should refer to the bibliographic sources you use in your assignment. A list of References must be presented at the end of the report listing all sources cited, in

Question 1

The analytical solution of laminar flow through infinitely long ‘parallel plates’ (also called plain channel) can be derived from the full 3-D Navier-Stokes (NS) governing equations via simplification with given boundary conditions. Fig. 1a below shows an upper plate driven flow with the bottom plate fixed. Fig. 1b shows a pressure drivenflow with both upper and lower plates fixed. The channel height is 2h (h=10 mm) and the flowing fluid is water at a constant temperature of 25 °C. Ignore the effects of gravity
