ABSTRACT

This paper investigates the heat transfer from a hot moving steel strip impinged by a laminar water-jet in the vicinity of the stagnation point with simulated film-boiling regions on either side. A two-dimensional Eulerian-Lagrangian method, in conjunction with a semi-analytical approach for large temperature gradients, has been shown to successfully solve the heat conduction equations with both advective and diffusive components. The study shows that under the impingement of the water jet the strip temperature at the stagnation point is initially depressed and subsequently rebounds strongly towards a steady state. The heat extracted by the water jet increases with increasing convective acceleration of the jet.
