In order to investigate the flow behavior of cooling water in scrubbing-cooling ring

especially at the outlet of the ring

a mathematical model for the fluid flow in scrubbing-cooling ring was established with Fluent

a software of computational fluid dynamics. The experimental study was carried out to measure the average velocity at the outlet of scrubbing-cooling ring to verify the mathematical model. The velocity of jet hole and slot was obtained from experiment and simulation. The numerical simulation result fits the experimental result well. It suggests that vortex exists inside the scrubbing-cooling ring because of the structure of the ring. The motion of vortex is most violent along the circumference of inlet in the inner chamber

so that the average outlet velocity of jet hole at the circumference of inlet is the minimum and the velocity at the circumferential position between two inlets is the maximum. The distribution of average outlet velocity of slot at circumferential position is the same with that of jet hole.
