Abstract


In this work, we investigated the accuracy of our in-house program based on blade element and momentum theory (BEMT). The main purpose of the program is to extract optimized blade geometry for a horizontal-axis-type turbine (HAT) used for tidal energy harvesting. The program was validated by comparing the computed power coefficients of a HAT and existing reference power coefficients for various tip-speed ratios (TSR). The program was also used to design a lab-scale HAT with a diameter of 80cm, and to compute the power coefficients of the HAT, which were validated through comparing with power coefficients computed by the computational fluid dynamics (CFD). The validation showed that the BEMT program provided reasonably accurate power coefficients. Other functions of the program, such as user-friendly pre- and post-processors, three-dimensional graphic display to examine the geometry of the HAT composted of the optimized blades, and finite element mesh generator, are demonstrated in this paper.
