ACADEMIC YEAR 2023/24 Assessment Brief Submission and feedback dates Submission deadline: Before 14:00 on 14/11/23 Is eligible for 2 calendar day late submission window Marks and Feedback due on: 14/12/23 N.B. all times are 24-hour clock, current local time (at time of submission) in the UK Submission details Module title and code : UFMFU7-15-3 Component and type : Report – Component A Assessment title: CFD Analysis of laminar and turbulent flow in a pipe Assessment weighting: 50% of total module mark Size or length of assessment: Maximum 8 pages (excluding references) Module learning outcomes assessed by this task: 1. Show a detailed knowledge and understanding of the theoretical background on which Computational Fluid Dynamics (CFD) is based and the iterative nature of the design/analysis process 2. Show a detailed knowledge of how CFD modelling techniques can be used to analyse engineering components 3. Demonstrate subject specific skills with respect to undertake analysis in an integrated CAD environment with an understanding of the underlying principles and their computing implementations 4. Demonstrate usage of the pre-processing, solve and post-processing stages of industrial standard CFD codes, including mesh generation and results validation. Completing your assessment What am I required to do on this assessment? You must work in pairs and each submit the same report. Once you have agreed with another student that you will work with them, you should access the page for this module in Blackboard, click on Coursework Groups and both Sign Up to the same group. You will have until 26/10/23 to do this. After this date any students that have not enrolled in a group will

be randomly allocated another student to work with. It is your responsibility to manage the workload within your pair. Under some circumstances, students will be allowed to work individually, but you must first seek authorisation from the module leader, in writing. Task 1 Construct a straight pipe flow which will be laminar and compare the CFD predictions for this scenario with those you would expect from classical theory for a fully developed flow i.e. parabolic velocity profile with known entry length and pressure drop per unit length. At the inlet to the pipe, you may assume a uniform velocity profile. You should use this opportunity to investigate the use of more than 1 mesh for the problem to ensure your results are mesh independent. Include images of the mesh in your report and discuss the settings you have used. Task 2 Construct a T-section pipe flow with one inlet and two outlets. Ensure the flow is turbulent at the inlet to the pipe and calculate the fully developed flow characteristics, from empirical/theoretical results (make sure the pipe is long enough to reach fully developed flow before reaching the T-section). Carry out a CFD simulation and compare your results with those from empirical findings. State the turbulence modelling assumptions that have been made by using the turbulence model you have chosen. For additional marks, experiment with a variety of different turbulence models, and compare the results and note their effect on the comparison with empirical results. The flow conditions for both the laminar and turbulent cases must be different from those in the tutorials (you may, for example, change the velocity, viscosity and/or pipe diameter). You must also use different mesh settings from those in the tutorials. Discuss potential sources of error and suggest reasons for any differences between your CFD results and those expected from theory. Source materials should be properly referenced and any plagiarism will be penalised, including students producing similar reports. Upload a report of no more than 8 A4 pages (minimum font 10) to Blackboard in pdf format Where should I start? Choose a partner to work with and sign up to a group on Blackboard. Decide what dimensions and fluid properties you will use, calculating Reynolds number to ensure the flow is laminar or turbulent as required. Calculate the entrance length to ensure the flow will be fully developed.

What do I need to do to pass? The majority of the marks are allocated in the “Theory & Methodology” and “Results, Discussion & Conclusions” sections (see marking criteria below). To pass you should address most of the “Aspects of Assessment” in these sections. How do I achieve high marks in this assessment? Ensure all “Aspects of Assessment” listed in the marking criteria below are addressed. How does the learning and teaching relate to the assessment? The tutorial sessions feed directly into the assessment and they have been designed to allow students to learn the software and include similar models to those needed for the assignment. The lecture sessions feed into the assessment by aiding understanding, allowing students to make more informed choices of the model settings and to better justify their decisions. What additional resources may help me complete this assessment?  Blackboard Discussion board  Feedback examples on blackboard  List of common mistakes on Blackboard  What do I do if I am concerned about completing this assessment? UWE Bristol offer a range of Assessment Support Options that you can explore through this link , and both Academic Support and Wellbeing Support are available. For further information, please see the Academic Survival Guide . How do I avoid an Assessment Offence on this module? 2 Use the support above if you feel unable to submit your own work for this module. The most common form of AO for this type of assessment is students producing similar reports to other groups from both this and previous cohorts. To avoid this, do not ask others to see their reports or agree to share your own report. The SafeAssign database will detect similarities and students that have shared their work will be treated the same as those that have plagiarised work.

1. In line with UWE Bristol’s Assessment Content Limit Policy (formerly the Word Count Policy), word count includes all text, including (but not limited to): the main body of text (including headings), all citations (both in and out of brackets), text boxes, tables and graphs, figures and diagrams, quotes, lists. 2. UWE Bristol’s UWE’s Assessment Offences Policy requires that you submit work that is entirely your own and reflects your own learning, so it is important to:  Ensure you reference all sources used, using the UWE Harvard system and the guidance available on UWE’s Study Skills referencing pages .  Avoid copying and pasting any work into this assessment, including your own previous assessments, work from other students or internet sources  Develop your own style, arguments and wording, so avoid copying sources and changing individual words but keeping, essentially, the same sentences and/or structures from other sources  Never give your work to others who may copy it  If an individual assessment, develop your own work and preparation, and do not allow anyone to make amends on your work (including proof-readers, who may highlight issues but not edit the work) and When submitting your work, you will be required to confirm that the work is your own, and text-matching software and other methods are routinely used to check submissions against other submissions to the university and internet sources. Details of what constitutes plagiarism and how to avoid it can be found on UWE’s Study Skills pages about avoiding plagiarism .
