| Abstract |
This study aimed to present the experimental results of two types of turbines and attachments
used in a hydro-compact generator. Two Horizontal Spiral Turbines (HSTs) with blade angles
of eighteen and twenty-one degrees, respectively, and a three-blade turbine were tested and experimented
in a laboratory at five levels of water flow rate ranging from 1–2 m/s. After the efficiency
and torque values of each turbine were identified, they were installed in two 200 W power generator
systems: (1) with a “diffuser” attachment; and (2) with an “in-line+diffuser+nozzle chamber” attachment,
and tested in a local irrigation canal with 1.2 m/s. The results from the laboratory indicated that
the HST with a twenty-one degree blade angle had 38.10% efficiency at the water flow rate of 2 m/s.
It could reach 120.0 rpm and produced 212 Nm of torque. The results from the field experiment
revealed that the combination of the power generator with the twenty-one degree blade angle HST
and the in-line + diffuser + nozzle chamber attachment was the most efficient, with 284 Nm of torque
at 108 rpm and could generate 67.63 W of electrical power. When the water flow rate of the irrigation
canal reached 1.5 m/s, it could reach 114 rpm and generate 129.2W. This hydro-compact generator
set is suitable for irrigation canals with a water flow rate ranging from 1–1.5 m/s. |
