Chernyavskiy A. Geometrical simulation of composition and phase transition surface of multicomponent systems state diagrams

Geometrical simulation of figurative point and phase transition surface of multicomponent system state diagram without limitation in components using multidimensional descriptive geometry methods is considered in the thesis. The solution of this problem enables to estimate phase transition temperature of multicomponent system for any figurative point. Algorithms of figurative point construction and algorithms of phase transition surface geometrical simulation by cylindroids and conical surfaces for multicomponent system using proper phase transition curves of constituent two-compound systems state diagrams with one common component as source data are developed. The program, developed using VBA-software for AutoCAD-system and based on analytical description of mentioned algorithms, enables to simulate composition of the multicomponent system and to estimate its phase transition temperature resting on state diagrams of constituent two-compound systems with one common component.
