Abstract
Abstract Starting from the technical and economic need to study the erosive effect of flowing electrolyte-solid mixtures (slurries) in detail, statistical methods have been applied. For this reason an abrasion pot has been used as an experimental tool. The experiments have been realized according to special factorial designs which have varied the levels of four important cause variables for sulphuric and hydrochloric acid. The evaluation by means of variance, regression and covariance analyses leads to concrete results which show clearly, for instance, the functional connection between the examined cause variables, which could partly be determined only qualitatively, and the material abrasion. The scientific and technological validity of the results given by statistical analysis will be discussed. In some cases, phenomena have been detected which cannot yet be explained in a scientific or technical way. The most important advantages of the application of mathematical statistics in the study of complicated technical systems are, among others, the complete and reliable information obtained for the existing interactions, the reduction in experimental expenditure and the determination of unknown phenomena enabling researchers to conduct systematic subsequent examinations.
