【摘要】 尾焰是一种复杂的非均匀气体辐射源,它作为一种典型的选择性辐射源,是红外模拟工作中非常重要的一部分。将采用粒子系统结合C-G谱带模型法,不仅逼真地模拟尾焰的不规则外形,还能实现尾焰红外辐射能量的数值计算。更多还原

【Abstract】 Aircraft plume is a complicated inhomogeneous gas radiation source. As one kind of typical selective radiators, its simulation is very important in whole infrared radiance simulation project. It is a new method to simulate infrared radiance of aircraft plume by combining the particle system which has been widely used to simulate irregular objects within visible spectrum and C-G algorithm which is always be used to engineering calculate the infrared radiance. The results not only obtain a realistic image of aircraft plume’s irregular shape, but also realize infrared radiance value computation.更多还原
