RETRACTION: Numerical Investigation of Entropy Generation on Micropolar Trihybrid Nanofluid Flow with Blood as Base Fluid in a Channel

RETRACTION: Y. Mehmood, A. Alsinai, M. Bilal, S. Iqbal, A. U. Khan Niazi, and N. Faisal, “Numerical Investigation of Entropy Generation on Micropolar Trihybrid Nanofluid Flow with Blood as Base Fluid in a Channel,” Journal of Mathematics, 2024, 9583109, https://doi.org/10.1155/2024/9583109. The above article, published online on 15 July 2024 in Wiley Online Library (https://wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Jen-Chih Yao, and John Wiley & Sons Ltd. The retraction has been agreed due to computational errors identified by an external reader, where the results were found to be incorrect because of the use of an incorrect value for the rheological parameter, the Prandtl number. After assessment by the Chief Editor, the error affects the results and conclusions presented, and the article is therefore retracted. The authors disagree with the retraction.
