Математичне моделювання та оптимізація теплових процесів у робочій камері устаткування для термічної переробки органічних відходів

Abstract

A comprehensive, multifactor 3D mathematical model of heat and mass transfer processes in the working chamber of equipment for the thermal processing of organic waste (e.g., a pyrolysis reactor) has been developed. The model is based on a system of partial differential equations that accounts for the simultaneous effects of heat conduction, convection, and radiation, as well as nonlinear phase transformations (drying, pyrolysis). The numerical implementation and verification of the model confirmed its adequacy (±5% convergence). Based on the modeling results, optimal operating modes were established, which allow for a 22% reduction in the temperature difference within the waste layer and ensure potential energy savings of up to 15%. The findings have high practical significance for the design of energy-efficient and environmentally safe equipment.
