Abstract

Purpose.  Development of a method for protection of atmosphere against pollution by burning solid rocket propellant within the moving railway carriage.  Create a calculation method to substantiate the effectiveness of  the proposed method of protection on the basis of numerical modeling of impurity scattering processes in the atmosphere.  Methodology.  To solve this problem developed a numerical  model  based  on  the  application  of  multivariate  equations  of  mass  transfer.  For  the  numerical  integration  of  pollutant transport equation was used implicit  «change  –  triangle»  difference  scheme. When constructing a difference scheme physical and geometric cleavage of the transfer equation is carried out in four steps.  Unknown value  of pollutant concentration at each step of cleavage  is  determined  by  the  explicit  scheme  –  the  method  of  point-to-point  computation.  When  conducting  computational experiments  considered  the  speed  of  the  wind  flow,  the  speed  of  the  train,  the  process  of  emission  of  chemically  dangerous substances and  neutralizer.  On the basis of the numerical model a computational experiment to assess the level of air pollution  if burned  in  a  moving  railway  carriage  of  dangerous  goods.  The  calculations  for  application  of  the  neutralization  of  combustion products of solid rocket propellant. Findings. An effective way to protect against contamination of the atmosphere in the emission of hazardous substances from a moving rail  car. A numerical model that allows to quickly calculate the air pollution in the event of an accident during transport of solid rocket propellant, as well as to calculate the rational parameters of the process of neutralization of pollutant. This model can be used for serial calculations modeling the different emergency scenarios.  Originality.  A new way to protect the atmosphere from contamination by release of hazardous substances from a moving railroad  car. Developed a numerical model that allows to evaluate the effectiveness of the proposed method of protection taking into account those physical parameters that  affect this process.  Practical  value.  An  efficient  numerical model, so  called  «diagnostic  models»  were  considered  for  rapid calculation  of  the  level  of  pollution  of  the  atmosphere,  and  the  atmosphere  is  provided  a  method  of  protection  in  emergency situations, in the case of solid rocket propellant transportation by railway.
