Engineering Physics Annotation << Back APPROXIMATE ANALYTICAL SOLUTION OF DIFFUSION PROBLEM OF VOLATILE COMPONENT OF VAPOR PHASE IN SIMPLE DISTILLATION APPARATUS D.V. FEOKTISTOV, V.S. LOGINOV Approximate analytical solution of diffusion problem of volatile component of vapor phase in simple distillation apparatus is obtained. The applicability limit of the obtained solution is determined. On the example of distillation apparatus, the problem of volatile component concentration distribution in vapor phase from the interphase boundary to the outlet branch for distillate steam is solved. Keywords: Mass transfer, diffusion, volumetric flow rate, concentration. E-mail: dmitrytpu@inbox.ru
