  1. 1. BY MR.VINAY P. SHENDE   M.Tech. (EMS) 4th Semester Under the Guidance of Prof. R.E. THOMBRE Deptt. Of Mechanical Engineering R.C.E.R.T. Chandrapur. A FIRST PRESENTATION ON PERFORMANCE EVALUATION OF FUNNEL TYPE SOLAR COOKER RASHTRASANT TUKADOJI MAHARAJ NAGPUR UNIVERSITY NAGPUR – 2010-11
  2. 2. INTRODUCTION <ul><li>Fire wood is used in almost all rural area around the world. This leads to consequence such as 1. Loss of forest area 2. Loss of fertile soil caused by erosion 3. Desertification 4. Increase of poverty and conflict 5. Smoke exposure. </li></ul><ul><li>Solar cookers are an important contribution towards halting the deforestation process and preserve the environment. 1) It helps in fighting poverty. 2) There is no CO 2 emission which is the main agent responsible for climate change. 3) The population becomes less dependent on charcoal. 4) Families spend lot of less money. 5) There is pay back on the investment after only few month of using Solar Cooker. 6) Cooking with Solar Cooker is hygienic. </li></ul>
  3. 3. LITERATURE SURVEY <ul><ul><li>A.V. Narasimha Rao, S.Subramanyam </li></ul></ul><ul><ul><li>[1] has discussed the role of vessel inside the </li></ul></ul><ul><ul><li>cooker. </li></ul></ul><ul><ul><li> Based on result, conclusion are ; </li></ul></ul><ul><ul><li>1) Putting the vessel on lugs make the bottom of vessel to improve the heat transfer. </li></ul></ul><ul><ul><li>2) Reduction in cooking time is possible. </li></ul></ul><ul><ul><li>3) Improve cooker performance without involving much extra cost. </li></ul></ul>
  4. 4. <ul><ul><li>Tarig A. Al-Azab, M.Q. Al-odat, F.M Al-Hussien </li></ul></ul><ul><ul><li>has performed the experimental investigation of box type solar cooker with finned pot and unfinned pot. </li></ul></ul><ul><ul><li> The experimental result show that ; </li></ul></ul><ul><ul><li>1) Cooker temperature can be increased by </li></ul></ul><ul><ul><li>using finned cooking pot. </li></ul></ul><ul><ul><li>2) Cooker efficiency can reach 45% for finned cooking pot and 40% for Unfinned pot. </li></ul></ul>
  5. 5. <ul><ul><li>C. Lertsatitthanakorn </li></ul></ul><ul><ul><li>has performed the experimental determination of energy efficiency of Conical Solar Cooker. </li></ul></ul><ul><ul><li> The experimental result show that ; </li></ul></ul><ul><ul><li>1) Sensible efficiency is about 20% </li></ul></ul><ul><ul><li>2) The maximum temperature obtained in the pot containing 2 lit of water is 92 0 C. </li></ul></ul>
  6. 6. <ul><ul><li>V.V.S. Murty & Preeti Kanthed </li></ul></ul><ul><ul><li>has study the thermal performance of a Solar Cooker having </li></ul></ul><ul><ul><li>phase change material as transparent insulation. </li></ul></ul><ul><ul><li>The experimental study shows that ; </li></ul></ul><ul><ul><li>1) PCM is observed to posses a good transmittance and insulation property and hence they are useful during charging and discharging process. </li></ul></ul><ul><ul><li>2) During charging process, as the PCM material melts, it allow’s the solar radiation into the cooker. </li></ul></ul><ul><ul><li>3) During discharging as it solidifies, the thickness of insulating medium increases with time and the rate of heat loss from the system also decreases and hence the heat energy retains for a longer time inside the PCM Solar Cooker. </li></ul></ul>
  7. 7. <ul><ul><li>R. Gayapershad, S.T. Dladla and M.J. Brooks </li></ul></ul><ul><ul><li>has conduct performance evaluation test on </li></ul></ul><ul><ul><li>sunstove unit and Ishisa box unit with tracked & </li></ul></ul><ul><ul><li>untracked condition. </li></ul></ul><ul><ul><li>Result show that ; </li></ul></ul><ul><ul><li>Sunstove unit reached the maximum temperature of 57 0 C and 55 0 C for tracked and untracked condition respectively. </li></ul></ul><ul><ul><li>Ishisa box unit reached maximum temp. of 72 0 C and 61 0 C for tracked and untracked condition respectively. </li></ul></ul><ul><ul><li>3) Tracking improve performance resulting in highest final temp. and cooking power. </li></ul></ul>
