  • Abstract:
  • This research involves the application of Computational Fluid Dynamics (CFD) in optimizing the thermal performance of brick kiln and brick soils. In this research four popular turbulence models – SST k-ω, Realizable k–ε, Standard k-ω, and RNG k-ε – to simulate the complex, turbulent flow and heat transfer within a brick kiln. Our primary objective is to identify the most effective model for accurately predicting thermal profiles and flow patterns that can impact brick quality and thermal efficiency. The study involves developing detailed 3D CFD models of the kiln, incorporating design configurations, kiln geometry, and brick arrangements. We analyze the predicted temperature distributions, airflow patterns, and heat transfer obtained from each model. Our findings reveal that the SST k-ω model demonstrates superior accuracy in capturing the intricate interplay of turbulence, combustion, and heat transfer within the kiln. It provides the most realistic predictions of temperature profile. Compared to the other models, SST k-ω exhibits superior near-wall performance and accurately captures the complex flow dynamics, leading to a better understanding of combustion efficiency and design formation. The SST k-ω Model is applied to investigate the thermal characteristics of various brick soils, including Brown Earth Soil, Hill/Mountain Forest Soil, Degraded/Grey Brown Podzolic Soil, Mountain Meadow Soil, Red/Yellow Podzolic Soil, and Alluvial Soil. Four key thermal parameters - mean thermal dispersion, effective thermal conductivity, thermal diffusivity, and thermal boundary resistance - are determined for six different types of soils. These parameters are crucial for understanding heat transfer during bricks production. The results indicate significant variations in thermal properties among the different soils. Among these, Brown Earth Soil emerges as the most suitable soil for brick manufacturing, as it experiences consistent uniform heating and also ensure high-quality brick production. Optimized heat transfer helps to reduced fuel consumption and minimizing production costs. The findings provide valuable insights for brick kiln design and soil selection, contributing to enhanced efficiency and sustainability in brick production.
