This paper introduces the designed calculation course of improvement of the mixed turbine impeller by applying computational aided design/computational fluid dynamics method for hydraulic machinery. Taking the HL220 turbine impeller as an example, the cavitation characteristic of the impeller inlet flow under the large flow was analyzed. Then, some approaches are presented to improve the performance...
With the adjustment of energy strategy, the demand of natural gas as clean energy will increase dramatically. Because of the uneven regional distribution of natural gas resource in China, the transportation pipeline networks have been developing quickly in recent years and the pressure of the pipelines is also becoming higher and higher. The pressure energy in the pipelines is enormous. A novel cycle...
