Investigation into the Flow of Gas-Solids during Dry Dust Collectors Exploitation, as Applied in Domestic Energy Facilities – Numerical Analyses

Abstract

The paper presents the results related to the simulation of dust-separating tangential cyclones: single cyclones of various geometries, and an axial multi-cyclone with fixed geometries and components. Its goal was to apply low-cost analyses for cyclones in industrial realization. Therefore, the presented research was applied with simulation methodology as a problem of Computational Fluid Dynamics. The models were analyzed using SolidWorks Flow Simulation software. The presented dust collectors are real-life objects, applied in industrial facilities. For a multi-cyclone, the increase in the number of blades, from 5 to 8, together with the change in the angle of a blade’s pitch i.e., 30° and 45°, resulted in dust concentration along the internal walls from just 10% for 5 blades up to c.a. 37.5% for 6 blades, and c.a. 50% for 8 blades, whereas the dust concentration in the device’s central part equals c.a. 20% for the last option. The model validation draws attention to the potential applicability of the software in flow issues alongside common and more complex numerical environments.

Adaptive Optimization Method for Prediction and Compensation of Thin-Walled Parts Machining Deformation Based on On-Machine Measurement

“…Many types of commercial finite element software can predict the machining deformation of parts before engineers carry out the machining of expensive large-scale thin-walled parts to avoid unnecessary machining deviations. These packages are, for example, Ansys, ABAQUS, Advantage, and SolidWorks [ 19 ]. But FEM model is generally inefficient in predicting the deformation of thin-walled parts, which is difficult to meet the demand for timely response and analysis in the machining process.…”

The Behavior and Removal of Condensable Particulate Matter in Flue Gas in a Multi-Field Force: A Modeling and Experimental Study

“…Researchers focused on electrostatic precipitators, developing a turbulent diffusion model that incorporates electrostatic transport effects in order to study the motion and sedimentation behavior of particles within the precipitator. The findings suggest that particle sedimentation in the reactor is primarily due to the combined effects of electrostatic migration and turbulent diffusion [15,16].…”

Use of Infrared Imaging Techniques to Investigate Thermal Losses of Flat Plate Solar Collectors

“…One of the most promising areas of renewable energy sources is solar energy. The energy flux emitted by the sun is a great example of an ecological and renewable energy source next to wind farms, photovoltaic and photothermal installations with water-flowing turbines (Maćkowiak et al 2023). The electromagnetic wave spectrum includes light visible to the human eye, UV radiation and infrared.…”
