An isotropic, homogeneous packed‐bed reactor is modeled as an array of sinusoidal periodically constricted tubes (PCT). The effective asymptotic bed‐Sherwood number has been calculated for mass transfer at large Péclet number with a constant wall concentration and creeping flow hydrodynamics. The bed friction factor has also been calculated. The results for these macroscopic bed quantities depend upon two ratios of the microscopic PCT period length, average radius, and sinusoidal amptitude.
