Description
Summary:Based on the previous investigations, regression equation for calculating the profile losses was found by the least squares based on the analysis of the profile losses nature and using mathematical optimization techniques. This equation makes possible to define the profile loss of axial turbine more accurate than the existing models and equations. It allows the calculation of profile loss values in the axial turbine that differ from the actual value by 10±61% with a probability of 95%. The obtained equation is not only superior to other loss models in statistical criteria, but it also considers the increasing number of factors affecting the profile losses.
