【Abstract】 This paper presents a new multi-parameter and multi-object nonlinear genetic optimal coupled inversion method coupling an genetic algorithm with an anisotropic turbulent model to calculate the jet ratio and jet angle of a buoyant jet with variable density.This method considers optimal dilution effect and lowest energy consumption by embedding the jet model and operation energy consumption equation into the genetic algorithm,and obtains optimal multi-parameters through multi-object optimization.The results show that the inversion method has advantages of jet parameter optimization that enhances jet water mixing with environment water and reduces energy consumption.更多还原
