Combustion Physics Group

This is an IOP special interest group, which is a community of IOP members focused on a particular discipline, application or area of interest. 

Special interest groups allow members to connect and share knowledge and ideas. The IOP funds groups to deliver a range of activities including events, prizes and bursaries. All of our groups are driven by members.  


About the group

As a special interest, member-driven group, we provide a forum for the discussion of the physical aspects of flames, ignition, detonation and related topics.

We are interested in these fields at a fundamental level and in the context of the practical use of wanted combustion processes in engines, boilers and other systems.

We also focus on unwanted combustion, like fires and explosions. 

Interest in the physical aspects of combustion continues to increase. We started in 1973 and have a good mix of industrialists and academics.

On the diagnostic side, two of the main tools for flame study are:

  1. the spectroscopy of flames 
  2. optical methods based on external light sources

Almost all the diagnostic techniques are physical. 

Lasers

One interest area is the increased use of lasers. This includes optical techniques linked to combustion like:

  • holography
  • fluorescence
  • Laser and Phase Doppler anemometry
  • Particle Image Velocimetry
  • coherent anti-Stokes Raman spectroscopy
  • Infrared Absorption Spectroscopy
  • Rayleigh Scatetring

We are also interested in the use of lasers for ignition and heating.  

Electrical aspects of combustion

The combination of electrical discharges and plasma jets with flames, along with spark ignition, are growing fields in combustion. 

Hybrid electrical and combustion devices are likely to become more important as the cost of fuel increases. 

The physical properties of low temperature plasmas have been embraced as an interest of the group at the request of leading workers in the field. 

Environment

Combustion instabilities, nitrogen oxides (NOx) and particulate emissions have led combustion to be associated with:

  • acoustics
  • scattering of energy

Fluctuations in energy prices and concern about the environmental impact of combustion processes have prompted appreciation of the relevance of combustion and heat transfer to the development of high efficiency appliances with reduced environmental impact. It has also highlighted the use of poor fuels and lean mixtures. In this way, the group contributes to efforts for low and zero carbon emissions and sustainable energy, including hydrogen and renewable fuel combustion.

Economy

The need for economy has renewed interest in topics such as sensing, feedback and control in combustion systems at the applied level. It has also increased focus on modelling combustion processes at a fundamental level, both in laboratory systems and in practical devices using combustion for heat generation.
