Abstract
This article presents a solution to the problem of determining the local heat flux density during cooling of a high temperature surface with a water jet. The solution takes into account the flow rate of the water jet and the diameter in the conditions of a transient boiling fluid. A local physic-mathematical model of moving strip's laminar cooling on a discharge roller table was compiled. Regions of jet impingement, film boiling, convective and radiative cooling in air are considered in this model.
