Three different micro-combustor geometries were computationally simulated using premixed methane air-fuel in quartz micro-combustor with different configurations in order to determine the optimal micro-combustor design for the highest efficiency. The study was conducted to determine the design and characteristics of flame stabilization behavior in the micro-combustor. ANSYS Fluent application software was used to simulate the models. Premixed fuel of methane-air is used to stabilize the flame with a stoichiometric ratio of 0.6. The design of micro-combustor is modified by creating backward steps in the model, in order to create a recirculation zone to slow down the flow, which intends to stabilize the flame at center of the micro combustor. The model was analyzed for different inlet velocities, ranging from 0.5 to 2 m/s, of the premixed fuel. It is clear from the analysis that a micro-combustor with one backward step stabilizes the flame with highest efficiency for different inlet velocities.

If successful, it can provide stable income and food security for eighty percent of the world’s poor living in rural areas. However, many poor rural farmers face multiple challenges to agricultural success, threatening their food security, income, and livelihoods. This study aimed to investigate and assess the challenges related to farming methodologies and work practices of small and marginal farmers in a rural village located in Rajasthan, India. An ethnographic, naturalistic study was conducted. Results indicated significant challenges to agricultural outcomes, including lack of necessary agricultural technologies, excessive expenses related to machine rentals (e.g., tractors, threshers), selection of soil nutrients based on intuition, destruction of crops by animal invasion, inconsistent electricity supply for agricultural needs, and lack of roads. One of the most pressing issues was the need for low-cost machinery, particularly a multi-purpose thresher, to significantly reduce excessive manual labor and expenses. A cost-efficient multi-grain thresher is introduced that runs on renewable energy and provides safety measures in the feeding mechanism, making it easy to use. This technology can lessen the strenuous physical exertion of farmers and laborers, also increasing their income.
