Turbomachinery Laboratory Website

The Turbomachinery Laboratory conducts basic and applied research into important problems of reliability and performance of turbomachinery — rotating machinery that extracts or adds energy to fluids. That’s everything from classic Dutch windmills to the space shuttle’s main engine turbopumps and compressors that move natural gas through the distribution system.

The Turbo Lab’s acclaimed Turbomachinery and Pump Symposia (TPS) is held annually in Houston, Texas, and its sister event, the Asia Turbomachinery and Pump Symposia, biennially in Singapore. Both feature a world-class exhibit hall and cutting-edge technical program.
