Mass Heat Transfer Measurement

In this chapter, the mass/heat transfer data from the turbine blade in the linear cascade with tip clearance are presented and analyzed in detail. The experiments are conducted using the heat/mass analogy and the naphthalene sublimation technique on the pressure, suction and tip surfaces of the turbine blade, at different clearance levels, mainstream Reynolds numbers, and turbulence intensities, respectively. For each case, at least two runs are performed to obtain repeatable data. Detailed information on the data selected to present in the chapter is listed in table 4.5.
