Conclusions
- Basic characteristics of IDF are explained with its applications.
- The visible appearance of the flame can be divided broadly into two zones
(i) Blue zone
(ii) Luminous zone. - The blue zone height increases with MR together with a reduction in luminous zone height. This can be attributed to the better entrainment and mixing of annular jet by intense turbulence generated by the central air jet.
- A linear empirical relationship is obtained between the non-dimensional flame height and MR which will be useful in the preliminary design of compact IDF based combustion systems.
