Method for minimizing the circuit diffusion in the numerical model ofaerodynamics

Through linearization of the trajectory of a fluidparticle on a fragment corresponding to a difference cell, and as a result of natural variables associatedwith the trajectory of particles, as well as the use of the differences against the flow, theconvective terms were approximated with minimization of the circuit or artificial diffusion. Thetest calculations confirm this result. It is shown that the proposed computational technique is suitablefor use in conjunction with the method of simple iteration.
