PhD Opportunity in Fire Engineering: Investigating Performance of Water-Based Fire Suppression

Applications are invited for a fully funded PhD scholarship (up to three years) in the Department of Civil and Environmental Engineering (University of Canterbury UC, New Zealand), under the main supervision of Dr Andres Valencia and co-supervision of academics of the fire engineering group at the UC. The project will be undertaken in close collaboration with Fire and Emergency New Zealand, who are providing funding support.

Description

Water is the most widely used agent for fire suppression, yet critical questions remain on how to optimise delivery methods for different fuels and scenarios. This PhD will focus on experimental and analytical investigations of water-based suppression systems, with emphasis on suppression performance, which can include:

  • Firefighting hose streams: studying suppression against well-defined fires (e.g. known heat release profiles) and streams (e.g. well-known droplet distribution and flux).
  • Sprinkler systems: studying dispersion and suppression against fires (e.g. known heat release profiles.) Characterizing dispersion flux.
  • Emerging technologies (optional depending on additional funding and external collaborators): exploring the feasibility of drone-mounted water delivery systems for rapid initial attack.

The student will conduct laboratory-scale suppression experiments using fuels with clearly defined burning characteristics and heat release rate profiles. Experiments will be designed to expose fires to precisely characterised water fluxes, allowing quantitative assessment of suppression effectiveness. In parallel, the student will develop and apply analytical modelling frameworks (e.g., Valencia et al. 2021a and Valencia et al. 2021b) to interpret results and generalise findings beyond the lab scale. The results will directly support the development and refinement of standards and codes of practice, such as the NZ firefighting water supplies code (e.g. SNZ PAS 4509).

Expected outcome

The successful candidate will:

  • Develop experimental protocols for assessing suppression effectiveness with hoses, sprinklers, and novel platforms.
  • Quantify relationships between water application rate, droplet characteristics, and fire suppression outcomes.
  • Provide data and insights to inform design standards, operational guidelines, and emerging technologies for fire services.
  • Present results at leading international conferences and contribute to peer-reviewed publications.

Candidate Profile

Preferred applicants will have:

  • A strong background in fire engineering, mechanical engineering, fluid dynamics, or related fields.
  • Demonstrated experimental skills, ideally in combustion, heat transfer, or suppression systems.
  • Strong analytical and coding ability (Python/Matlab/R) for processing experimental data.
  • Interest in translational research that links laboratory experiments with real-world firefighting practice
