Paper Title
A Numerical Simulation of The Inner Boundary Layer of A Circular Water Jet Impingement Over A Heated Plate

Abstract
The objective of this paper is to study the near-wall behaviour over a heated steel plate in jet impingement cooling in run-out table (ROT). A Computational Fluid Dynamic (CFD) model was developed using ANSYS-Fluent for a circular watter jet impingment over a heated surface. A two dimensional model for asingle jetwith a velocity of 1.5 m/s was implemented. The water is impinged vertically on a stationary hot steel plate with an initial temprature of 700oC. Thek-ω SSTturbulant model was used, and mesh refinment critera was discussed to best capture the viscous sublayer region near the wall. Non-dimensional velocity profile at different zones along the plate were plotted and compared with the law of the wall. The CFD results have been compared to the the available von Karman constantfor various conditions.
