The Computational Fluid Dynamics (CFD) results were validated quantitatively and qualitatively with the experimental results (using Particle Image Velocimetry (PIV)). The standard k-ε adopted curvature correction and enhanced wall treatment of y+ â�� 1.2â��1.7 appears as the best validated model, producing minimal deviation with comparable flow structures to the experimental cases. © Springer Nature Singapore Pte Ltd. 2017. date: 2017 publisher: Springer Verlag official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85028965858&doi=10.1007%2f978-981-10-6463-0_23&partnerID=40&md5=824a438c4264d9d38c1e7d01d2ae474a id_number: 10.1007/978-981-10-6463-0₂₃ full_text_status: none publication: Communications in Computer and Information Science volume: 751 pagerange: 259-273 refereed: TRUE isbn: 9789811064623 issn: 18650929 citation: Nordin, N. and Abdul Karim, Z.A. and Othman, S. and Raghavan, V.R. and Adzila, S. and Md Seri, S. and Md Taib, I. and Ramli, Y.
