Applications for this type of turbines range from small gas turbine engines for light helicopters through airborne and land-based auxiliary power units, automotive powerplants, turboexpanders, mechanical drive steam turbines, solar powerplants working with organic fluids and turbopumps for liquid fuel rockets. Depending on the application, the turbines may be of the radial, axial or mixed flow type. The combination of small blade heights and high Mach numbers and turning angles makes the design of these turbines particularly arduous, especially if the rotor inlet Mach numbers are supersonic. Extensive design experience and the use of advanced design tools can overcome these problems as was demonstrated by the group of lecturers who were selected for this course. The lectures addressed primarily turbine design and development engineers. But testing techniques and advanced calculation methods were also discussed. Learn More

Solid particle erosion problems are of great concern in gas turbines, steam turbines, boilers, fluidized beds, aircraft engines and many other systems. Erosion may cause a significant decrease in the operating lifetime of gas turbine engines or other systems operating in dusty environments or when ash particles are present, as in coal gasification. Particle trajectory studies provide information on particle impact and location, and erosion studies indicate the amount of material removed with each particle impact. The course presented the principles involved and the state-of-the-art in erosion prediction for engines subjected to solid particle ingestion. Particle deposition may have as detrimental an effect on turbine performance as blade erosion. The mechanism of particle formation and particle adhesion to the blade surfaces were discussed in depth with particular emphasis on fluidized bed and coal-fired turbine applications. Learn More
