Mathematical Modeling of the Heat-Transfer Intensity by the Methods of the Theory of Experiment Design

The conditions that should be realized in the process of continuous mould casting of alloys on the basis of simultaneous account for the factors determining the formation of the near-wall gas interlayer and the heat transfer are elucidated. In this case, forced rejection of the alloy from the wall by a gas blown into the zone of moulding of a casting is provided. In the general case where the gas is blown through a porous wall, near-wall gas cavities merging into a gas film are formed at the working surface of the wall. The problem posed in this investigation is a typical multifactor problem, in which it is quite appropriate to use the method of the theory of experiment design.
