BS-III

The experimental set-up consists of two concentric stainless-steel spheres. The inner combustion spherical combustion chamber has an inner diameter of 563 mm and a thickness of 42 mm. The outer sphere has an inner diameter of 640 mm and a thickness of 4 mm. A thermal fluid flows between the two spheres for raising the chamber temperature up to 573 K and to maintain this temperature uniform.

Dimensions :

• Inner diameter: 563 mm
• Internal volume: 95 L
• Optical windows diameter: 400 mm
• 8 fans from 100 to 12000 rpm

Pressure / Temperature :

• 300 bar / 300°C

 

Operations at this facility began in 2008 for various research projects such as combustion, flame instabilities, turbulent flame with an initial homogeneous and isotropic turbulence and effect of spray on combustion.
