Coursework Overview

The waste heat from an organic rankine cycle is used as activation energy in a biodigestor as shown in the figure below.

Design an optimised heat exchanger to facilitate heat transfer between the organic rankine cycle and the biodigester. Make use of ANSYS Workbench, ANSYS Fluent and ANSYS DesignXplorer to conduct the study. Investigate the effect of uncertainty in the design parameters on the performance of the heat exchanger using the Six Sigma Analysis from the ANSYS DesignXplorer toolbox.

The working fluid (fluid 2) entering the biodigester is water and must not exceed 38 °C.

Each student will have a unique set of data provided to them by the module tutor. This unique data set includes:
• the atmospheric temperature
• working fluid 1 specification
• working fuild 1 inlet temperature

Coursework Tasks

The following tasks are to be completed on the chosen design problem:

• Provide a description of the design. Include a drawing/sketch/model of the heat exchanger clearly showing the parameters.
• Discuss the model setup in ANSYS Workbench indicating the different steps required to perform the analysis. Explain how the response surface is created focusing on the theory of generating reduced order meta-models.
• Present and interpret the results obtained from the response surface.
• Present and interpret the results obtained from the response surface optimisation. Clearly indicate the implications for the design and the optimal values of the selected parameters
• Investigate the range of performance as the design and operating parameters vary by performing a Six Sigma Analysis in ANSYS Workbench.
• Conclude the report with the major findings.
