An Analytic Model for Dispersion of Rocket Exhaust Clouds: Specifications and Analysis in Different Atmospheric Stability Conditions

Abstract

This paper brings the first results concerning a new analytic model to evaluate atmospheric dispersion in rocket launch scenarios, namely Generalized Integral Laplace Transform Technique for Rocket effluent dispersion model. The model is constituted by three different modules, being two pre-processors (micrometeorological parameters and deposition parameters) and the dispersion program. The dispersion calculations are made through the Generalized Integral Laplace Transform Technique solution of the two-dimensional, time-dependant, advectiondiffusion-deposition equation. The results show a set of simulations using data from the Chuva Project from the Centro de Lançamento de Alcântara for both stable and unstable planetary boundary layers, in order to evaluate model performance and illustration.

Rocket emissions representation in atmospheric air‐quality models: The short‐range atmospheric transport and reaction of gases released by solid propellant engines

“…Both studies addressed the dispersion problem for numerical air-quality models. Some effort was made to obtain an analytical model for this problem (Bainy et al, 2015), but the solution does not take into account the complex topography and wind, which is characteristic of the CLA region (Pires et al, 2015).…”
