โœฆ Synopsis


This brief discussion of the quasi-steady reacting one-dimensional boundary layer shows that for fuel surface temperatures T s only slightly in excess of the ambient gas phase, there can be a relationship between the fuel flow M and the DamkiShler number ti which is neither S-nor C-shaped. For some conditions there can be a unique value of 6 which divides the M -T s plane into four regions.

The problem of isothermal diffusion in a variable molecular-weight binary gas mixture is considered for the case when the process occurs in a laminar boundary layer. Viscosity and diffusion coefficient are assumed constant. Solutions are given for both forced and free convection at large Schmidt num

An analysis is developed for predicting extinction of-the diffusion flame that is established when an oxidizing gas flows about the nose of a vaporizing fuel body. Use is made of the limit of a large ratio of the activation energy to the thermal energy at the flame for the overall combustion process
