The impact of Cross Ignition process (CI) in the gas turbine operation and environmental issue is still investigated for extending the efficiency of gas turbine engines and meanwhile decreasing the environment pollution.This paper presents various constructive influential parameters and analysis of their related interaction during CI. A developed computational model for determination of cross-ignition time (CIT) is proposed, based on previous relevant models for thermal analysis and for distinguishing of heat fluxes in combustion processes. Due to the first analysis of theoretical results, experimental investigation for various operating conditions were essential to validate the developed computational model of the CIT. Thus, a simple experimental test rig is designed for this purpose, and for validation of certain conditions of the computational model. Meanwhile, for expanding the investigations in higher energy conversion and reducing expensive testprocedures, that are conducted during critical test running, a new strategy is proposed for simulating the thermal heat fluxes throughout the burners compartment model by implementation of Computational Fluid Dynamic (CFD). Finally, new constructive criteria based on the validated investigations will enable the future generation of gas turbine combustors to operate in critical conditions.
