Determination of appropriate configuration of submerged vanes using fuzzy TOPSIS optimization
Submerged vanes are river-training structures installed vertically in front of intake ports to exclude sediment at water intakes. The performance of submerged vanes depends on their dimensions, configuration and shape. This study was aimed at numerically investigating the effect of vane configuration on sedimentation in a 90° intake from a straight channel, and determine an appropriate configuration for installing the vanes. Simulations were done using the FLUENT mathematical model, and the fuzzy technique order performance by similarity to ideal solution multi-objective optimization method was used for choosing the appropriate configuration. All simulations were done for the three discharge ratios of 0.11, 0.16 and 0.21. The results showed that a longitudinal distance of nine times the vane height, a transverse distance of three times the vane height and 25° angle of attack are the appropriate parameters for the configuration of submerged vanes to control sediment in front of intake ports.
