This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the Author. After publication, the author noted that the paper inadvertently used data from the previous Standard k-ε model, resulting in the numerical simulation of Reynolds number 2300-3500 in the paper, which also affects the conclusions of the paper. The author agrees with this retraction and deeply regrets these errors and apologizes to the editorial board and readers for any inconvenience caused.
