Analytical Study of Biomass Cloud Particles considering the Lewis number effect

In this paper, the effect of Lewis number on the structure of one-dimensional flame of biomass combustion is analyzed. This effect can be observed by considering the non-unity Lewis numberin the governing equations. the value of the characteristic Zeldovich number is too large and theequivalence ratio is larger than unity 1 u f ³ The flame structure consists of three different zones which are, a preheat vaporization zone a reaction zone that consists of gas and Char combustion and aconvection zone. The obtained results from the present model declare that the temperature and burningvelocity profiles are extremely affected by the various Lewis numbers
