Round 1

Reviewer 1 Report

This paper extends the low-order noise prediction methodology to predict the leading-edge and the trailing-edge noise for a fan with forward skewed blades. The predicted results considering the sweep variation along the blade span are improved by comparing with the measured ones. The leading-edge and trailing-edge noise spectrum could be correctly revealed. The results and analysis of this paper is quite thorough and are worthy of publication.

 

Specific comments:

  1. In line 103, it is written that “the turbulent length scale Lf in Fig. 4 (a) and the mean square of the velocity fluctuations u2, in Fig. 4 (b)”, the description is not consistent with arrangement in Figure 4.
  2. Is it possible to adopt unevenly distributed strips to reduce the number of the segments?
