Return to List

Open Posted: 13 Nov 19. Closes: 08 Jan 20 Available: Semester 1 (Feb - Jun)

Semester 1 2020 project
 ** UQ students only **

 

Suited to: final year or Masters students in Mechanical or Mechatronics Engineering (UQ). If you are selected, the project will be your final year thesis / Masters project topic so you must be eligible to enrol in the appropriate unit/s (eg. ENGG4011 for final year Mechanical Eng students) during Semester 1 2020.


The successful applicant will receive a $3,000 scholarship + academic credit for enrolment/assessment (6units - UQ ME thesis, 4units - UQ Mechatronics thesis or Master of Eng students).  

If selected, you must be available to work on the project onsite for 3-4 days/week (3 days/week for 4unit projects or 4 days/week for 6unit project) during Semester 1 2020 (working around lecture timetable).


APPLICANTS NOTE: you must include your academic transcript/s inside your resume - unofficial transcript for current degree + transcript for past degree - Masters students) + your student ID number.  Combine your resume and transcript/s into one doc/pdf.  We cannot progress your application until you provide this info in your resume.


UQ ME and ITEE students
 must have a study plan approved before their application can be accepted by CEED. You must make an appointment/contact an academic advisor to get your study plan reviewed and approved.

ME students: contact Dr Bill Daniel for academic advice - [email protected]

Mechanical/Mining students must then provide approved academic advice document to Dr Christopher Leonardi prior to enrolling in ENGG4011 - [email protected]

CEED Coordinator for ME & Mining is Dr Christopher Leonardi.

For UQ ITEE students - you must have a study plan approved before your application can be accepted by CEED - to ensure you can enrol in the correct thesis/project unit for a CEED project. You must make an appointment with an academic advisor to have your study plan reviewed and approved.

Project Background / Description

RWC products are designed to meet national and international standards. To achieve this certification requires stringent testing of product performance. This is particularly important on products used as safety devices (thermostatic mixing valves, temperature & pressure relief valves, etc.) These tests are typically conducted in our Australian-based NATA accredited laboratory and are completed both prior to product implementation and throughout the product lifetime.


TMVs (Thermostatic Mixing Valves) are a core part of RWC’s product range. They are used to regulate hot water systems at a safe operating temperature as well as scald protection in the case of cold-water supply failure. This is achieved by the mixing of hot and cold water using a thermostatic element.


All RWC products are performance tested and pre-set using end of line automatic test rigs (setters). With TMVs, these setters check that the basic operation and performance of the valve meet the product specification and set the mixed outlet temperature. Conditions for testing are simulated using chilled and hot water supplies, which are fed into a valve with varying pressures.

Objectives / Tasks / Project Outcomes

The selected student will work with RWC Engineering and Production staff to conduct a feasibility study into the use of air as an alternative medium to test and pre-set on the production line. This will include:

  • Review of current Australian standards to understand any constraints on production testing.
  • Literature review of existing / documented testing methods.
  • Design and conduct testing (CFD and practical) to validate the operation of TMVs and thermostatic elements using air instead of water.
  • Prepare a costing and Capex to procure suitable equipment to be built and to conduct air testing trials.
  • Quantitative analysis and cost comparison of the proposed setting system in comparison to the current (water) setting system.

 

Desired Project Outcome / Deliverable: 


A feasibility study on the use of air instead of water as a medium to check valve performance. This is to include tests validating valve operation in response to air and a comparative analysis of setting methods using air versus water.

Skills / Experience Required

  • CAD design (Autodesk Inventor)
  • Application of Computational Fluid Dynamics – Autodesk CFD
  • Keen interest in engineering design and production engineering, controls system design, heat transfer and thermodynamics
  • Understanding of / ability to design to specified Standards
  • Excellent oral and written communication skills
  • Ability to work effectively within a professional team environment
  • Very good time management skills
  • Reliable
  • Good problem-solving skills
