Where:
He accounted for the heat. As the air compressed, the temperature skyrocketed. He modeled the oil injection points , simulating how fine droplets of lubricant would absorb the heat of compression, keeping the system from melting down. The Moment of Truth Where: He accounted for the heat
At pressure ratio = 4.5, speed = 3000 rpm: - Volumetric efficiency = 82.3% - Adiabatic efficiency = 76.1% - Leakage fraction: blowhole = 8.2%, radial = 5.4% The Moment of Truth At pressure ratio = 4
