Role of solar indoor cooker with natural circulation in mitigation of carbon emissions

The present study introduced a novel 'thermosyphon heat transport device' (THTD) for solar cooking. The numerical analysis included the response and flow pattern of THTD and its counterpart simple closed thermosyphon (SCT). The response of SCT is deteriorated by 38% compared to THTD as multiple recirculation zones are present in the flow region. Further, a redesigned cooktop THTD integrated with a parabolic dish reflector emerged as an efficient design. In India, both firewood and LPG cooking leads to alarming pollution level, which can be proficiently cut down by implementing cooktop THTD as it can minimise 14.19 Mt of CO2 discharge. Additionally, gains carbon credit for the same.
