90-07: Determination of the Turbulent Lewis Number From Experimental Data for Testing

90-07: Determination of the Turbulent Lewis Number From Experimental Data for TestingSome of the difficulties and anomalies encountered when computing separate heat and mass transfer coefficients from wet cooling tower fill test data are presented. The Lewis analogy, which has historically been used to relate the sensible and evaporative transfers, is examined in light of this data.

This preparation is based on the knowledge of what the system contains

and modern high heat transfer procedures illustrated with actual hands-on field examples

and with their degradation

has developed a modeling computer program called CooliSS

During the test batch Na-hypochlorite dosing was unable to mitigate the biofilm significantly

For the past several years

These alternate tube designs were analyzed under a variety of flow conditions in controlled settings

today's equipment now addresses the concentration and handling of separated solids

recent environmental legislation has increased restrictions on industrial chromate discharge

Proper polymer monitoring allows one to understand true demand factors versus other artifacts that might negatively impact control

especially in the high pH environments common to many of today's cooling water systems

not only of the subject cooling system
