The questions of the surface quality on the heat transfer and the Leidenfrost temperature in this area have not yet been properly answered. Previous investigations showed that such an influence may exist. The main aim of this study is therefore to verify this hypothesis by using statistical methods and to construct exact mathematical model describing given problem. The cooling experimental stand using a steel testing plate was developed and high temperature experiments (up to 1200°C) with various surface roughness parameters were accomplished. The paper presents measured experiments, data evaluation and processes and the influence of surface manufacturing methods, e.g. rolled, burnished, fine and rough grind surface, on cooling process. 1
