AB  - The atmospheric pollution is one of the most dominating phenomenons 
  now-a-days. It is generated partially by warm gases emitted by transporting 
  vehicles and industrial activities and equally has origin the degradation of 
  the environment in general and the quality of air in particular. This study 
  concerns the homogenous compressible flows with constant viscosity. It consist 
  of an experimental validation and modelling of the diffusion of a passive scalar 
  in an interacting turbulent flow with two heated oblique air jets inclined at 
  an angle of 45° in relation to the principal direction. The two jets emission 
  holes are circular with a diameter of 5 mm and spaced out by 40 mm. This study 
  treats the influence of the initial velocities of jets on the diffusion of the 
  temperature field. The problem was tackled using the calculation codes of Gambit-Fluent 
  to simulate the diffusion of a scalar. The results show that the flow temperature 
  decreases with the increase of the Reynolds number and the scalar sustains lesser 
  and lesser influence on the longitudinal flow. The numerical results are in 
  account with the experimental results.
