Abstract
This article used the CFX method to study the circumferential flow and heat transfer characteristics of the anti icing flow path in the inlet casing under typical icing conditions. It explored the distribution of anti icing hot gas flow characteristics and the uniformity of heat transfer along the circumferential flow, and obtained the flow and heat transfer characteristics of key positions in the anti icing system. The calculation results indicate that under the calculation conditions, the hot gas velocity and temperature in the gas collection chamber exhibit a circumferential symmetric trend, and decrease along the circumference. The distribution of hot gas velocity and temperature in the blade is symmetrical along the circumference, and the velocity increases along the circumference, while the temperature is opposite. The inlet flow rate of the blades increases along the circumference, and the blade with the highest inlet flow rate is located at 180 degrees along the circumference of the hot air inlet of the inlet casing. In addition, the temperature of the hot air at the inlet of each blade decreases along the circumference.The velocity and temperature of hot air inside the cone exhibit an axisymmetric trend along the circumference.
