Energy storage product nozzle design scheme

How many nozzles are regulated in a compressed air energy storage system?

Only one nozzle is regulated in the optimal regulation process. The air storage pressure of the compressed air energy storage system gradually decreases during the energy release process. In order to make the turbine work efficiently in non-design conditions, it is necessary to adopt a reasonable air distribution method for the turbine.

How many nozzles should be regulated in an optimal nozzle governing method?

An optimal nozzle governing method should contain as few nozzles as possible. More throttle valves should be fully open for the optimal method. Only one nozzle is regulated in the optimal regulation process. The air storage pressure of the compressed air energy storage system gradually decreases during the energy release process.

Does nozzle inlet pressure change affect aerodynamic performance of ng turbine?

In studies of NG turbine, researchers have mainly focused on the mathematical modeling and control optimization methods in the NG process, but there are fewer studies on the effect of nozzle inlet pressure change on the aerodynamic performance of the turbine.

How to optimize nozzle inlet pressure under variable woutput conditions?

Based on the RS model, the multi-island genetic algorithm (MIGA) is used to obtain the optimal nozzle inlet pressure under variable Woutput conditions with the maximum specific work ( w) as the optimization objective, and finally the optimization strategy of NG is derived.

How to design a nested nozzle ejector?

For the nested-nozzle ejector design, each nozzle must be optimized to provide effective work in a certain operating range. Moreover, the shared suction, mixing, and diffusing chamber parameters must be compromised to fit both ejectors.

How many nozzles are there under rated woutput conditions?

Under the rated Woutput conditions, the number of fully open nozzles, fully closed nozzles and regulated nozzles is 2, 1, and 1 under the BP of 10.0 MPa and 9.0 MPa, respectively. While the number of fully open nozzles, fully closed nozzles and regulated nozzles is 3, 0, and 1 under the BP of 8.0 MPa, respectively.
