Abstract

Abstract

The flow state of airflow in the bend passages is analyzed. The control equation and boundary condition of the gas phase flows are determined. The mathematical model of the finite difference and the computer program are presented. The effect of geometric parameter of the passages on the resistance are analyzed by theoretical computations and experiment, and calculated results and experimental data is good agreement.
