this is vector plots of main flow in different cross can be seen from the image,main flow is rotating.Can it cause particles to rotate?nnmain flow has mass flow rate of 1.1 kg/s and temperature of 600 is solved as a compressible flow.operating pressure is 101325.gauge pressure in pressure outlet boundary conditions is set as 0.nafter flow is solved,ndensity is about 0.57,ninlet velocity is about 60 m/s,nin the elbow velocity is about 110 m/s,nbig part of domain has velocity of about 50 m/s,nmach number is between 0.004 to 0.25.nare they correct and logical?n
