The authors developed a high expansion ratio radial inflow turbine for a helium liquefier of 100 L/h capacity for use with a 70 MW superconductive generator. The following results were obtained from this development work: 1)Very stable and highly reliable operation was maintained through use of ...

Flow expansion within a nozzle is naturally 3D phenomena; however, the use of side walls controls the expansion approximating it to a 2D flow confined. An experimental study of nozzle performance traditionally uses the stagnation conditions and the area ratio of the diverging section of the tunnel...

However, considering the complexity of the mixed refrigerant ratio, there is still much room for improvement in this process. Ahmad Naquash et al. [29] added a new high-boiling component hydrofluorocarbon into the pre-cooled mix refrigerant to reduce energy consumption and increase the exergy ...
Analysis of a wide range of data obtained from very fast depressurization experiments for water and freon has demonstrated that the heterogeneous nucleation factor correlates very strongly with the ratio of the initial liquid temperature and the critical temperature of the fluid.关键词: BLOWDOWN HETEROG...
