'Firewire'

The picture is taken as part of a wider experimental study on Combustion of Bio-fuels. The initial set of experiments includes method to stabilise a Methane flame. The premixed of Methane and Air flows through a circular nozzle. The flame is stabilised by a circular wire. During combustion process the temperatures at the flame reach 2500°C. The flame can be seen in blue shade. The radiance from the combustion products is visible in orange shade. The picture is taken with a Nikon D80 camera, with an 18-200 VR lens. The aperture and the shutter speed are varied depending on the requirements. The concentric bright yellow circles are formed as the wire oscillates due to the instabilities developed in the flow during combustion process. The picture is in its original form.
