Pressure losses in apparatuses with swirling flows
Abstract
We consider the method of calculating the pressure in apparatuses with swirling flows, depending on the different materials. The influence on the calculation of pressure losses in the two-phase swirling flows of various parameters for the organization of fuel combustion processes, mass and heat transfer, dust collection. Dependence of pressure drop on the amount of energy consumed and the choice of blowers for apparatuses with swirling flows. The causes of pressure drops in two-phase swirling flows are given and listed. The loss of gas kinetic energy in apparatuses with twisted and counter twisted flows of gas suspensions exceeds losses from all other causes, that only this loss should be taken into account. The peculiarities of design and pressure losses in vortex pressureless apparatuses are considered. The results of investigating the dependence of pressure losses in the apparatus on the air flow rate through the vortex chamber and the results of investigating the effect of the ratio of flow rates through the apparatus channels are presented.
