Carbon-on-tow filters - Pressure drop effects and vapor phase retention

MARTIN P.; NGUYEN T.; KAO J.; FINLEY A.

Philip Morris USA, Richmond, VA, USA

A mathematical model was developed to describe pressure drop changes and retention of condensible vapor phase components for carbon-on-tow/cellulose acetate (CA) dual filtered cigarettes. The model uses the dynamics of vapor flow through the cylindrical ...
