The main purpose of this study is how water injection on a micro gas turbine engine contributes to the recovery of power output. Especially in summer, the density of air tends to decline, compared with one in winter. This phenomenon causes the decline of power output. Water injection is known for an effective tool of recovery of power output. The experiments have been performed to investigate the behaver of power output of a micro gas turbine due to the change of injection ratio. The injection ratio has been varied within the range of 1.03% to 4.49%. The evaporation rate of water droplets is calculated based upon mass transfer between water droplet and surrounding air flow.
The prediction method has been reviewed by comparing the predicted performance with the measured data.
