Dimensionless Film Momentum Transfer Coefficient in Relation to the Analogy among Transport Phenomena

抄録

An M0 number, which is a dimensionless formula of the film momentum transfer coefficient m0 and reverse of the dimensionless film thickness of flow, was proposed. The M0 numbers deduced from the known theoretical and experimental equations of momentum transfer phenomena for flows in a pipe and around a sphere were compared to the Nusselt numbers, Nu, and Sherwood numbers, Sh, for the corresponding heat and mass transfers, respectively, and a good analogy was found among them. The phenomena of momentum transfers were also simply explained using m0 and the M0 number. The author expects that these findings might be useful for improving the education of fundamental chemical engineering, food chemical engineering, and biochemical engineering.
