4 Jan 2023 | Abstract: | Tesla turbines are an attractive but less explored area in low-power
applications. This article presents an experimental investigation of a
centimeter scale Tesla turbine in bi and unidirectional outlet configuration
with compressed air at 6 bar. The turbine’s performance is enhanced by
approximately 38% for a unidirectional outlet configuration. Furthermore, we
also investigate the electrical power of the turbine in a bi-directional outlet
configuration by coupling the turbine with a generator. Despite achieving
higher performance in unidirectional outlet configuration, we observe
substantial losses at the inlet we use for the experiment. To illustrate and
improve the losses, we numerically investigate the turbine inlet at a total
pressure and temperature difference of 2 bar and 50 degree K, respectively.
Subsequently, we design two more nozzles and compared their performance with
the nozzle we used in our experiment. Our findings suggest that nozzle 3
performs the best in delivering the highest Mach no and uniformity across the
slits. This observation would help optimize the nozzle suitable for the Tesla
turbine. | Source: | arXiv, 2301.01483 | Services: | Forum | Review | PDF | Favorites |
