If the compressed air flows into the
flame tube without being decelerated, it may cause serious problems on combustion stability and high total pressure loss.
Taking the 3D solid model of loop-type
flame tube of combustor of a certain type triaxial gas turbine as reference, a 2D axisymmetric model is built by the way of area average, and the discrete computational domain is also built on the basis of structured grid.
Following the initial performance runs the first engine was dismantled, the coated components were installed and six windows were mounted on the engine enabling optical access to the main hot end components including the combustion chamber inner
flame tube, nozzle guide vanes and the turbine rotor blades.
the torch along the length of the
flame tube "hikes" up.
Science pavilion organiser Robin Wheldon-Williams said: "Also known as the standing wave
flame tube, or simply
flame tube, is a physics experiment demonstrating the relationship between sound waves and sound pressure.
A sonic nozzle at the top of the
flame tube allows pressure in the vessel to be raised while maintaining the throughput of reactant gas.
The buring velocities of R-152-air flames recently have been measured using both the
flame tube method (Jabbour and Clodic 2004) and the spherical bomb technique, with both pressure rise and flame imaging used to extract the burning velocity (Takizawa et al.
Heater has a top mounted gas burner that fires downward through a centrally located
flame tube. The resulting heat from the flame heats the falling water, which comes in contact with the bed of packing rings where heat transfer occurs.
