Physical and Mathematical Modeling and Computer Analysis of Radial Impellers for Chemical and Power Engineering, taking into account Ecology

This article is devoted to mathematical models for the study of natural frequencies, static stresses of radial impellers with cover disk for chemical and power engineering, taking into account ecology and their modeling by the finite element method. General form and mathematical model based on the finite element method of a radial impeller with a covering disc from Schiele & Co (Germany). For a numerical study, this wheel is accepted in the technical field in different computing software systems. For example, commercial systems such as ANSYS WORKBENCH, SOLIDWORKS and initiative software packages (BLADIS+) [1] for solving problems of statics, vibrations and calculating the resource of different technical systems. Calculations of natural frequencies and static stresses of a radial impeller of 10 blades for chemical engineering are presented. The results obtained in this work can be safely assumed the study of changes in natural frequencies and static stresses of turbomachines are relevant at the design and refinement stages. These computer calculations make it possible to significantly reduce the volume of expensive experimental studies that pollute the environment, reduce design time and improve ecology.
