Analysis of turbulent wall jet impingement onto a moving heated bodyCoşanay, HakanÖztop, Hakan F.Gür, MuhammedBakır, EdaHeat transferImpinging flowMoving blockMoving wallWall jetPurpose: The purpose of this study is to make a numerical analysis of a wall jet with a moving wall attached with a heated body. The hot body is cooled via impinging wall jet. Thus, a jet cooling problem is modeled. The Reynolds number is taken in three different values between 5 × 103 ≤ Re ≤ 15 × 103. The h/H ratio for each value of the Re number was taken as 0.02, 0.04 and 0.0, respectively. Design/methodology/approach: Two-dimensional impinged wall jet problem onto a moving body on a conveyor is numerically studied. The heated body is inserted onto an adiabatic moving wall, and it moves in +x direction with the wall. Governing equations for turbulent flow are solved by using the finite element method via analysis and system Fluent R2020. A dynamic mesh was produced to simulate the moving hot body. Findings: The obtained results showed that the heat transfer (HT) is decreased with distance between the jet outlet and the jet inlet. The best HT occurred for the parameters of h/H = 0.02 and Re = 15 × 103. Also, HT can be controlled by changing the h/H ratio as a passive method. Originality/value: Originality of this work is to make an analysis of turbulent flow and heat transfer for wall jet impinging onto a moving heated body.Emerald Publishing2022Articlehttps://rdlopen.rawdatalibrary.net/r/munzur/2813https://doi.org/10.1108/hff-08-2021-05210961-5539enInternational Journal of Numerical Methods for Heat and Fluid Flowinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/2813
