ABSTRACT
This chapter focuses on gas-to-liquid (GTL) fuel, a liquid fuel derived from natural gas using Fischer–Tropsch synthesis and specifically tailored for aviation gas turbine engines. It presents part of the effort of the combustion team that was carried out in Texas A&M University at Qatar (TAMUQ) to look into spray characteristics of the GTL fuel. The present study was started as part of a consortium research work under the auspices of Qatar Science and Technology Park (QSTP) to evaluate the feasibility of using GTL jet fuel as an alternative fuel in aviation engines. An optically accessible spray experimental facility was developed and used to study the spray characteristics of several GTL fuels and the conventional Jet A-1 fuel. The spray characteristics of these fuels were investigated as it plays a major role in subsequent processes of evaporation, mixing, combustion, and emission in a gas turbine combustor.
