| Abstract: | Based on two-phase flow theory,the numeral solution of the mathematical simulation equation stood for gas flow drying process which refers to straw fuel in straight horizontal tube obtained by the standard four-step Runge-Kudra method.Test bed of pneumatic drying was established,and the test results were summed up by making single-factor test on the test bed.The results of simulating and single-factor test were coincided.The influences of initial moisture content and air temperature are analyzed. |
