Abstract

With the development of UV missile warning systems, there is a need to assess or predict the UV signature for missile. This paper shows an emission model for UV missile plume signature. The model computes the missile plume flow field distribution, takes into account CO-O chemiluminescence and hot particles emission in the plume, and analyses the influences of the alumina particles scattering. Plume flow field is computed by the RNG k-ε turbulence model with non-equilibrium wall functions. Alumina particles optical properties are calculated by using Mie theory and the particles are assumed a log-normal size distribution. Radiative transfer equation is solved by the discrete-ordinates method. The model is applied to a user-defined test case and compared with other UV plume emission signature models based on different algorithms, the result of comparison is coincident and satisfied.
