EXPERIMENTAL STUDY OF THE HYDRODYNAMIC MODE OF A WASTE REACTOR WITH AN ACTIVE SOLAR HEATING SYSTEM UDK: 628.477
Abstract
Today, the problem of waste is one of the social, environmental, and energy problems not only in our country, but also in countries around the world. The article proposes a thermal scheme for a device designed for the thermal processing of municipal solid waste using anaerobic fermentation based on solar energy. A schematic of the air duct for the waste reactor of the thermal processing unit has been developed. Taking into account the thermophysical properties of the hot air moving through the air duct, experimental studies of the hydrodynamic flow regime were carried out. Experiments were conducted with average air velocities in the waste reactor’s air duct: in the laminar flow regime at m/s, and in the turbulent flow regime at m/s, with average air temperatures ranging from . Based on the experiments, empirical equations describing the hydraulic resistance in relation to changes in the Reynolds number within the viscous-gravitational region of the turbulent flow regime in the reactor’s air duct were derived. The calculation results obtained from experimental research were simulated using the Fluid Dynamics Simulation software package.
