摘要
模拟燃烧器在不同的旋流数状况下,燃烧空间内部温度场和速度场的分布,分析燃烧器燃烧过程的火焰结构和火焰温度。模拟结果表明:要保证燃油能稳定燃烧且火焰分布合理,旋流数应选在1.584~4.705之间。
The distributions of temperature and velocity in the burner are simulated with different swirl numbers, and the structure and temperature of the flame are analyzed. The simulation results show that the steady combustion and reasonable flame distribution are obtained only when the swirl number is 1.584-4.705.
