Subject: turbine normalised total-to-static efficiency combust. as soon as the pressure ratio drops below 1.2, the turbine normalised total-to-static efficiency falls dramatically to values below 0.6

The total to static efficiency relates the work output of a turbine to the ideal work calculated from the total pressure at the turbine inlet to the static pressure at the turbine exit. This efficiency definition is appropriate if the kinetic energy at the turbine exit is a loss for the process. это то ли мощностной КПД, то ли КПД турбины по параметрам заторможенного потока, разбирайтесь сами |
