Enhancing Efficiency of Rural Cooking Stove: Numerical and Experimental Validation of Design and Development

Abstract

The study presents the design of a highly efficient cooking stove for rural applications, along with performance evaluation. Drawing on diverse literature, existing works were analysed to derive design enhancements. Utilizing SolidWorks and Creo, a model was constructed, followed by material selection and cost analysis using accessible market components. ANSYS Fluent enabled flow analysis for both optimal and real configurations, complemented by experimental tests for validation. Results underscore the stove's efficiency, evident in reduced wood consumption for cooking and decreased soot generation. Significantly, the system's heat transfer rate reached 11.67°C/min, outperforming open stoves at 3.42°C/min, while maintaining affordability at RM 415.34. Nomenclature = Temperature transfer efficiency for heat recovery = Temperature outside air before entering system = Temperature inside air after system heat transfer has occurred = Temperature inside air before system is switched on = Temperature Transfer Efficiency for Heat Loss
