Performance Test Of Charcoal Cook Stoves Expermentally And Using Ansys Cfd For Improvement

Abstract

Due To Poor Thermal Performance Of The Conventional Bare Metal Stove, Plenty Of Improved Cooking Stove Development Projects Have Been Introduced All Over The World Over The Last 14Years In Order To Improve Energy Consumption . All Improved Stoves Saved Fuel On Average When Compared With The Conventional Bare Metal Stove, And The Majority Also Lowered Total Emissions Released. The Conventional Stove, On The Other Hand, May Be Difficult To Replace Because It Had The Shortest Time To Boil, Which Is An Important Aspect For End Users. Using The Emission And Performance Test Protocol (Eptp Protocol), There Were Also Noticeable Differences In Stove Performance Between All Stoves. In This Work, Ansys 2012 Design Modular Is Used To Model Six Conventional Locally Available Cooking Stoves (Turumbe, Ethio, Obama, Hexagon, Bandira And Bare Metal) And The New Design Stove Geometries And A Computational Fluid Dynamics (Cfd)Analysis Has Also Been Carried Out For These Different Geometries Of Stove To Analyse The Flow Behaviour Of Gas, Heat Transfer Behaviour, Oxygen Mass Fraction, Volatile Mass Fraction And Co2Mass Fraction During The Cooking Period Using Autodesk Simulation Cfd 2012. For All Stoves The Computational Results Were Compared And Validated With The Experimental Data. The Experimental Data Were Handled By Using Wbt Excel Spread Sheet For All Cooking Stoves And The Analytical Analyses Were Done Only For The New Design Modified Stove (Ms).From Experimental Data Thermal Efficiency Result Was Found To Be 27.8, 22.6, 22.6,23, 25.47, 16 And 28 % For Turumbe, Ethio, Obama, Hexagon, Bandira, Bare Metal And New Design Modified Stove, Respectively. The Analytical Result Of The New Design Modified Stove Was Found To Be 27%. For All Stoves The Emission (Co And Co2) Results Were Compared And The Bare Metal Showed Large CoBy % Volume.
