the arrangement is studied using numerical simulation method for its influence on rectangular channel wall CaSO4 crystallization fouling deposition process. At temperature of 300 K
velocity 0.5 m·s-1 and CaSO4 concentration about 3.0 g·L-1
the influence of geometrical factors on the surface fouling deposition is analyzed
such as the length of circular vortex generators
arrangement
radius
and spacing. The results show that the fouling resistance decreases and then increases along the length of vortex generator and appears minimum at (4/8)H shocked strengths. It increases with the spacing of vortex generator
and for the spacing more than 55 mm the fouling resistance will gradually tend to that in smooth path. The fouling resistance increases with the radius of vortex generator. The same spacing and radius
length of (4/8)H
and arrangement on one side make the fouling resistance minimal.
