规则往复流中Wells透平自起动过程的数值模拟和实验研究

SELF-STARTING PERFORMANCE OF WELLS TURBINE IN REGULAR RECIPROCATING AIRFLOW

基于稳态透平切向力实验数据,在准定常流动假设下对规则往复流中Wells透平的自起动过程进行了数值模拟,数值模拟结果与实测数据的比较结果表明,该文建立的数值模拟过程可替代实验方法用以分析规则往复流中Wells透平的自起动过程。

In order to clarify the self-starting process of a wells turbine in a regular reciprocating airflow, a numerical simulation process was introduced, on the basis of the rational assumption of quasi-steady flow conditions. Subsequently, an experimental investigation on self-starting process was conducted in a computer-control reciprocating airflow test rig to verify the computational results. It can be seen from the comparison results that the measured data agree well with the simulated ones, which means that it is possible to predict accurately the self-starting process of the Wells turbine by computer simulation.
