Super Efficient Jet Engine and Gas Turbine Combustion

The scarcity and environmental costs of burning fossil fuel for transportation and other energy needs is a growing concern. Disruptive technology changes are needed to reduce fuel consumption in aircraft and peak power generation, and cut greenhouse gas emissions sharply. The gas turbine has been an enormously successful power plant for aircraft and marine propulsion, and electric power generation, due to its light weight, smooth and reliable operation, low emissions, and varied applications. Nevertheless, it is not very efficient in converting fuel energy to useful work due to fundamental thermodynamic limitations. Dr. Nalim has investigated alternative thermodynamic cycles and pulsed combustion systems for propulsion and gas turbine applications resulting in the development of a key new component called a wave rotor combustor.

Laboratory experiments and computer simulations are underway to verify the wave rotor combustor’s application and usefulness in industry. This translational research involves the collaboration of experts from IUPUI and industry in various disciplines. Dr. Nalim’s work on super-efficient gas turbine combustion can reduce energy and transportation costs while having a positive impact on climate change.

Professor Nalim’s development of a super efficient combustor is another example of how IUPUI's faculty members are TRANSLATING their RESEARCH INTO PRACTICE and making life better in our community and the world.
