Heat/Mass Transfer

Gas turbines have been widely used and will continue to be used into the next century as power generation sources and engines for propelling aircraft, ships, submarines, tanks, cars and other vehicles.

The challenge for engineers today is to bring the gas turbine engine to a new level. Fluid flow and heat transfer are primary concerns in modern gas turbine design, where highly efficient and durable turbine machines are sought. Even with current computer technology, experimental investigations remain a fundamental tool to help understand turbine fluid flow.

The combustion chamber and the turbine blades that follow the combustor experience tremendous thermal loads which directly affect the performance of the engine. In the Heat Transfer Laboratory at the University of Minnesota, we focus on the heat transfer to the blades caused by fluid flows and disturbances, such as passage, high turbulence and wake, separation, film cooling, etc. The methods used for the research are described in the following sections.
