These changes in enthalpy and element composition at the inner layer, combined with the sensitivities of the mass burning rate on such changes, finally induce a change in the stretched mass burning rate, which is studied in the last section. Deviations between theory and numerical simulations will...
Black carbon(BC) contributes directly and indirectly to the Earth's radiative balance change,and consequently,has impact on global warming as the second largest contributor after carbon dioxide.One of the major sources of aerosol emission from biomass burning is open burning of agricultural residues....
