Hydraulic Resistance of Tangential Swirlers

Resumo

The hydraulic resistance of nine tangential swirlers with rectilinear and sectional channels is measured. A comparison of the hydraulic resistance coefficients of the different swirlers is and it is established that the structural parameters of the swirlers and Reynolds number together exert a significant influence on the hydraulic resistance. It is shown that the resistance coefficient increases with increasing width of the swirler channel gap due to a decrease in the gas velocity and an increase of the force of viscous friction. A relationship for calculating the resistance coefficient of the swirlers is obtained.
