| Abstract: | The one dimensional mathematical model of the air drag in melt blowing process which has been put forward by Shambaugh et al is improved. The influence of the density and the specific heat capacity at constant pressure of polymer melt changing with polymer temperature on fiber diameter is studied. The power - law model is introduced as the constitutive equation. The influences of polymer volume flow rate, initial polymer temperature, initial air velocity and initial air temperature on fiber diameter are discussed. |
