Fluid loading, distribution and mixing in a microfluidic rheometer

Location: Bayswater, Melbourne, VIC

Duration: 5 months

Proposed start date: May 2019

Project Background

Haemograph is a biomedical start-up company based in Victoria. It is developing a novel device to measure properties of coagulating blood.

Within the device it is important to be able to introduce blood into the device easily, safely and reliably without introducing air bubbles or dead spots. The aim of this project is to develop a system for introducing the blood and having it be distributed through to the appropriate measurement channels.

This project is appropriate for an engineer (especially chemical or biomedical), scientist (especially chemist or physicist) or mathematician with a good understanding of fluid flow and fluid mechanics, especially within a microfluidic environment.

Experience with, or understanding of blood properties is not expected or required, and the intern will not be using blood as an experimental material.

Research to be Conducted

The research to be conducted includes:

  • proposing a layout for the various parts of the fluid flow during fluid loading
  • Testing and validating the parts separately (either experimentally or numerically)
  • Testing and validating the parts together (either experimentally or numerically)
  • Producing a proof-of-principle design
  • Demonstrating the design with appropriate model fluids.

Skills Required

We are looking for a PhD student with the following skills:


  • Excellent understanding of fluid flow
  • Excellent record-keeping skills
  • Ability to operate safely in a lab environment
  • Ability to work without the need for close supervision


  • Ability to produce CAD designs
  • Ability to perform CFD simulations or other numerical analysis
  • Ability to perform microfluidic fluid flow experiments

Expected Outcomes

Subject to negotiation and the intern’s progress the expected and desired outcomes include:

  1. A preliminary study proposing the layout for the overall loading system, identifying the features and components that can be optimised separately and proposing the testing required for each of the separate component
  2. Optimisation, validation and production of the performance of each of the separate component
  3. Production and testing of the overall design
  4. Integration with the rest of the Haemograph device
  5. A brief report outlining expected difficulties during the commercialisation and production stages

Additional Details

The intern will receive $3,000 per month of the internship, usually in the form of stipend payments.

It is expected that the intern will primarily undertake this research project during regular business hours, spending at least 20% of their time on-site with the industry partner.  The intern will be expected to maintain contact with their academic mentor throughout the internship either through face-to-face or phone meetings as appropriate.

The intern and their academic mentor will have the opportunity to negotiate the project’s scope, milestones and timeline during the project planning stage.
