a high-velocity flow of the blade’s pressure surface interaction According to the following figure, Is use of "a high-velocity flow of the blade’s pressure surface interaction" in the following sentences correct grammatically and conceptually? If it is not , kindly suggest ways to make it clearer. From Fig. 18(b) and (c), and Fig. 19(b) and (c), it can be seen that a high entropy generation region appears behind the TE portion of the blade because there is a high-velocity flow of the blade’s pressure surface interaction with backflow region and the low-velocity leakage vortex. TE=trailing edge My meaning of "a high-velocity flow of the blade’s pressure surface interaction with... " is "an interaction of high-velocity flow from the blade’s pressure surface with...".
