The turbine is a crucial component in harnessing ocean thermal energy(OTE), and the impact of the nozzle on turbine performance is significant.TC-profile nozzles have been proven to operate efficiently in air turbinesunder high-temperature and high-pressure conditions. However, their performancein ocean thermal energy conversion (OTEC) turbines usingorganic working fluids (low-temperature and low-pressure) still requiresfurther research. Therefore, we focused on a practical 100 kW OTEC turbineequipped with different types of TC-profile nozzles. Three-dimensionalnumerical models were established, and the simulation results demonstratedthat the turbine efficiency using TC-3A was generally higher thanother turbines, reaching an optimal efficiency of 89.4%. The turbine canoperate efficiently at deviations from the design point of + 10.27% or−31.39% in mass flow rate, ±3℃ in inlet temperature, and + 20% or−11.43% in rotor speed during off-design conditions. The results revealedthe adaptability of TC-3A nozzles to the OTEC environment and theirexcellent off-design performance. The study could provide valuable guidanceand references for the application of TC-type nozzles in the field ofOTEC turbines.
