چکیده
In the present work, numerical simulation and optimization was carried out to analyze mechanism of variable guide vanes (VGVs) a transonic compressor. A seven-stage compressor including three-stage VGVs studied. The were adjusted individually jointly under different IGV opening degrees. Changes in performance shock wave analyzed, coupling effect VGV joint adjustment summarized. Aiming at maximum efficiency, turning angles optimized. novel phenomenon found wherein can affect not only its own that adjacent downstream blades, but also upstream blades. Incidence blades are improved, those deteriorated. weakens shock-induced boundary layer separation. optimal solution for is combination solutions single adjustments. improves efficiency by 0.2–1.93%

متن کاملNumerical optimization of guide vanes and reducer in pump running in turbine mode
The main limitation of centrifugal pump running in turbine mode is lower efficiency at part load operating conditions as compared to conventional hydro turbines. To enhance the utilization of pump as turbine (PAT) in mini/micro hydropower plants, it is very important to improve its performance with some low cost modifications. The part load efficiency of PAT can be improved by guiding the flow ...

A multiobjective, reliability-based design optimization method for computationally intensive problems is proposed. In this method we use a genetic algorithm to facilitate the multiobjective optimization. To further improve the convergence of the genetic algorithm, we augment it with a local search. Reliability analysis is performed using Monte Carlo simulation. Quadratic design response surface...

An unsteady two-dimensional finite-volume solver was developed based on Van Leer’s flux splitting algorithm in conjunction with “Monotonic Upstream Scheme for Conservation Laws (MUSCL)” limiters to improve the order of accuracy and the two-layer Baldwin-Lomax turbulence model was also implemented. Two test cases were prepared to validate the solver. The computed results were compared with the e...
