A mathematical model for airflow and heat transfer through fibrous webs
journal contribution
posted on 2009-04-23, 13:20 authored by Mamdud Hossain, Memis Acar, Weeratunge MalalasekeraWeeratunge MalalasekeraA mathematical model based on computational fluid dynamics has been developed
to investigate the airflow and heat transfer through fibrous webs. The model is based on the
porous media concept and involves solving equations for continuity, momentum, and energy.
A thermal energy equation is developed, which incorporates the heat of fusion of fibres in the
fibrous web. Local flow information such as air velocity, temperature, and melt fraction of
fibres is obtained from the simulations. An important outcome of the simulation is the
prediction of time required to melt fibres in the web under different working conditions.
This information can be used potentially in the design of through-air bonding process for
nonwovens manufacturer.
