摘要: Abstract With great interest, the authors have read comments made by Ghisu et al. on our recent paper [1] published in Renewable Energy. The severely criticizes methodology and results, which actually provide us with fortunate opportunity to discuss work more details complement work, thankfully this available space of scientific discourse provided Energy editors. In reply, we show clearly that all proposed lacks sufficient understanding Wells turbine modeling approaches, literature, state art research practices. We also could not distinguish between fully developed turbulent flow transitional around airfoils. It is evidently shown their concerns about entropy generation calculation method are meaningless light well-established practices CFD models minimization principles. Our reply structured a point-by-point style address raised discussion article help readers understand better details.
