3 Assessment Details

3.1 Module Learning Outcomes (MLOs) Assessed by Coursework

Knowledge & Understanding:

MLO1.  Relate knowledge of mathematics, statistics, natural science, and engineering principles to broadly defined problems relating to fluids and energy systems.

Intellectual / Professional skills & abilities:

Personal Values Attributes

MLO3.  Apply creativity and curiosity to analyse broadly defined fluids and energy problems reaching substantiated conclusions.

3.2 Coursework Overview

The assessment consists of two mechanical engineering projects (Project 1- Turbomachinery and Project 2-Heat Transfer) involving energy and fluids. After you have completed these two individual projects.

You must complete the two projects described on page 4 and submit a single digital file with your report.

3.3 Expected Size of Submission

You need to submit a technical report of maximum 12 page. The report should include figures, graphs and calculation. This is equivalent to 3500 words. Please note that if you submit more than this, only the first 7 pages of your submission will be assessed. A title, contents page and any reference will be included in this page count.

3.4 Referencing Style

You are to write your coursework using the Cite Them Right version of the Harvard referencing system. An online guide to Cite Them Right is freely available to Northumbria University students at

https://www.citethemrightonline.com/

3.5 Assessment Criteria

The marks for each component are described on Table 2

Project 1. Aerofoil and turbomachinery:

Using the NACA four-digit aerofoil series, design a blade or wing suitable for a specific application (e.g., wind turbine, aircraft wing, propeller, or any turbomachinery). Research and analyse online data for lift and drag coefficients of various NACA aerofoil profiles under different Reynolds numbers and angles of attack. Based on your analysis, recommend the most suitable aerofoil for the chosen application, justifying your choice with performance data and reasoning.

a) Research and Data Analysis: Define the chosen application and its specific requirements, such as efficiency, stability, or power output. Collect and analyse data for various NACA four-digit aerofoils from online resources or simulation tools, focusing on lift-to-drag ratio, stall characteristics, and other key performance indicators.

b) Design Justification: Compare the performance of different aerofoils based on the data collected and explain the rationale behind selecting the final aerofoil for the application. Highlight how the aerofoil meets the requirements of the chosen application.

c) CAD Design: Create a 3D model of the design using SolidWorks, incorporating the selected aerofoil profile. The model should be scaled to 1/100 and tailored to the application. Include detailed screenshots and a description of the design process.

d) Wind Tunnel Testing Setup: Describe the conditions required to test the scaled model in a wind tunnel of your choice. This should include specifications such as flow speed, Reynolds number, and adjustments for scaling effects. Justify the choice of wind tunnel and explain how the conditions will simulate real-world performance.

Project 2. Heat Exchanger:

A counter-flow heat exchanger is used to cool compressed air from 550 K to 315 K using water available at (290 + y) K. Note: The y is the last number of your student number. For example, w30027530 would give Y=0

a) Overall Heat Transfer Coefficient (U)

The convective heat transfer coefficient on the waterside is 1 kW/m²·K, while on the air side, it is 0.04 kW/m²·K. Assuming the thermal resistance of the tube wall is negligible.

-Calculate the overall heat transfer coefficient, U

-Determine the percentage increases in U if both the waterside and air-side convective heat transfer coefficients are doubled. Discuss the effect of the heat transfer coefficients on the Overall Heat Transfer Coefficient (U)

b) Heat Transfer and Area Required

Assume the mass flow rates of water and compressed air, respectively. Base your assumptions on real-world examples found in the literature. Then:

- Calculate the total heat transfer and determine the required heat transfer area.

-Critically analyse the calculated total heat transfer.

Discuss the practical considerations and design implications for implementing this heat transfer area within the heat exchanger.

c) Outlet Temperature with Reduced Water Flow Rate

Reduce the water flow rate. The heat transfer area and overall heat transfer coefficient remaining unchanged:

-Estimate the outlet temperature of compressed air. Use an iterative approach for the Log Mean Temperature Difference (LMTD), starting with an assumed outlet temperature. It is advised to use excel or MATLAB to perform the calculations, explain each step in the calculation.

- Discuss how temperature of compressed air changes.

d) SolidWorks Drawing

•     Draw a detailed 3D and 2D SolidWorks heat exchanger model using the area calculate in b), including critical features and annotations.
