In the.pre.e.t work, an alte.native.nume.ical me.hodology is de.e.ope. for a fast and e.fe.tive.simulation and analysis of the.comple. flow and e.e.gy conve.sion in Pe.ton impulse.hydro turbine.. The.algorithm is base. on the.Lagrangian approach and the.uns.eady fre.-surface.flow during the.je.-bucke. inte.action is simulate. by tracking the.traje.torie. of re.re.e.tative.fluid particle. at ve.y low compute. cost. Mode.n re.re.sion tools are.imple.e.te. in a ne. parame.e.ization te.hnique.of the.inne. bucke. surface. Ke.-fe.ture.of the.mode. is the.introduction of additional te.ms into the.particle.motion e.uations to account for various hydraulic los.es and the.flow spre.ding, which are.re.ulate. and e.aluate. with the.aid of e.pe.ime.tal data in a Laboratory Pe.ton turbine. The.mode. is applie. to study the.je.-runne. inte.action in various ope.ation conditions and the. to pe.form nume.ical de.ign optimization of the.bucke. shape. using a stochastic optimize. base. on e.olutionary algorithms. The.obtaine. optimum runne. attains re.arkably highe. hydraulic e.ficie.cy in the.e.tire.load range. Finally, a ne. small Pe.ton turbine.（150 kW） is de.igne., manufacture. and te.0}d in the.Laboratory, and its pe.formance.and e.ficie.cy ve.ify the.mode. pre.ictions.
