THE KENICS STATIC MIXER - NEW DATA AND PROPOSED CORRELATIONS

New results for wall-to-tube heat and mass transfer in a Kenics-type s tatic mixer allow a unification of extent data. Nearly universal corre lations are presented. They allow detailed comparisons with open tube designs. Heat transfer enhancement is greatest in deep laminar flow. E ven there, the Kenics mixers exhibit modest improvements when compared on the basis of equal pressure drop. Existing designs are not yet opt imized for heat transfer and studies at lower aspect ratios for the mi xing elements are recommended.
