ABSTRACT
The Gas Turbine Laboratory (GTL) at Ohio State University (OSU) secured its international recognition when in 1995 Dr. Michael Dunn moved from Calspan in Buffalo to OSU in Columbus and became a professor in the highly respected OSU Engineering School. He brought with him from Calspan the key facilities of its gas turbine jet engine research laboratory and key personnel. He has since added new cutting-edge test facilities to the OSU GTL. A shock tube short-duration test starts with the high-pressure driver gas rapidly expanding as a result of a controlled rupturing of the primary diaphragm, creating a shock wave. The test gas is instantly compressed and thus heated to a high temperature by incident and reflected shock waves. The OSU shock tube in Professor Dunn's GTL is possibly the largest and most elaborate of its kind.
