CFD Study of Tikikil Stove Performance and Effect

Tikikil stove is a family of rocket stove designed to properly fit the Ethiopian community. This book focuses on using Computational Fluid Dynamics (CFD) to predict the thermal and combustion properties of Tikikil stove. ANSYS FLUENT have been used as a tool to do CFD modeling of Tikikil stove. The result of simulation is used to calculate the thermal efficiency of the stove. The thermal efficiency of modified Tikikil stove using simulation is 34.52%; while the experimental result showed a thermal efficiency of 27%. Effect of secondary air inlet on Tikikil stoves thermal efficiency is another area covered in this book. The effect of secondary air inlets by putting four holes with diameter of 28mm above on stove mouth was studied. The first trial was to put secondary air inlets at 175mm above fuel bed, other four trials where done in 155mm, 145mm, 135mm and 125mm above fuel bed. The stove with secondary air inlets at a position of 125mm above fuel bed was selected because the thermal efficiency is better than the rest.
