Welcome to the TurboMachinery Laboratory of the School ofMechanical and Aerospace Engineering at Seoul NationalUniversity. The TML aims to advance the technologies related to various propulsion, power, and energy conversion systems. Current experimental and analytical research projects cover performance analysis of power generation systems, especially those using clean, renewable energy sources; aerodynamics, rotordynamics, and aeromechanics of turbomachinery; flow mixing in ejectors in gas turbines and fuel cell vehicles; development of small gas turbines for portable power generation; air-fuel supply systems for fuel cell automobiles; and electrohydrodynamics related to propulsion of small satellites and nano technologies.
