Thermal Characteristics of an Educational Coffee Roaster Using a Portable Gas Stove

Abstract

This study explores heat transfer through natural convection experiments and thermal simulations of an educational coffee roaster. Using a simple silicon rubber heater, students measure heat transfer coefficients, bridging theory and practice. The simulation of the roaster, powered by a gas stove, analyzes temperature distribution and heat flow, validated by experimental data. Results show that integrating experiments and simulations enhances students’ understanding of heat transfer, offering valuable insights into optimizing roaster dsign and heat efficiency, thus linking theoretical knowledge with practical application.
