Numerical Research of Physical and Chemical Processes at Polymeric Material Ignition by Several “Hot” Particles

Abstract:

The mathematical model of heat and mass transfer processes at polymeric material ignition by several metal particles heated to high temperatures was developed. Numerical research of integrated characteristic at the accounting of diffusive and convective heat and mass transfer in the oxidizer during the induction period was executed. Common effect of several local sources with limited power consumption on the main integrated characteristic of process – ignition delay time was established.
