To improve the working performance of early annular jet pump (EAJP), a streamlined (SAJP) was proposed. The flow field and EAJP SAJP with an area ratio (m) 1.75 were numerically studied compared, separately, by using combination Realizable k-ε turbulence model Schnerr–Sauer cavitation model. results show that efficiency is higher than EAJP, when (q) 0.30, maximum increase 1.2%. Furthermore, high-efficiency (q = 0.40~0.69) wider 0.36~0.57). There no separation low local pressure in SAJP, due...
To find the influence of suction chamber and throat inlet profiles on cavitation performance an annular jet pump (AJP), a numerical method using combination realizable k–ϵ turbulence model Schnerr–Sauer was applied. This paper comprehensively studied AJPs with polygonal line profile (POL) streamlined (STR). The results showed that efficiency (η) can be increasedby STR largest increase 1.4%. Since is smoothly connected in AJP STR, flow separation local low pressure did not appear. critical...
According to the B–H curve and structural dimensions of snubber by Fink–Baker Method, inductive voltage eddy current any core tape with thickness saturated regions are derived when accelerator breakdown occurs. Using Ampere's law, in each tape, lamination is equal arc current, relation for different laminations can be deduced. The total equivalent resistance obtained. transient model based on stray capacitance analyzed, solving process given detail. exponential time constant Then, maximum...
Turbo-generator stator's inter-turn short is a usual serious fault, there would have hidden big trouble for electric power system's safety due to lack of efficient protection. On-line monitoring generator's operate condition combined intelligence non-line identify technology presented observe fault in time instead poor function Longitudinal zero-sequence voltage and phase's current are analysis as stator winding's short's stable characters, mathematical model which build, Elman neural...
In this paper, an efficient method is proposed to calculate the capacitor placement in a distribution network with wind generators. The target find optimal locations and sizes of both fixed switchable capacitors minimize overall cost. First, formulation presented based on control vector model comprising reactive power outputs Meanwhile, necessary constraints are considered. Then, primary single-layer hybrid particle swarm optimization strategy solve mathematical formation. Further, fuzzy...
