Owing to the worldwide concentration on energy security, a recent trend of mix is adopted by gradually replacing fossil fuels with other renewable sources. Biodiesel has emerged as promising candidate. It renewable, nontoxic, and biodegradable can be suitable choice for undertaking this issue. produced via various procedures, e.g., dilution, microemulsion, pyrolysis, transesterification. The latter most utilized procedure given its effectiveness in which vegetable oils or animal fats short-chain alcohols are allowed react presence catalyst. Different oil feedstocks identified including edible, nonedible, algae-based biomass resources. Conventionally, homogeneous catalysts generalized biodiesel production because their high catalytic activity low cost, albeit, due wastewater generation during purification process product, separation problems, soap production, heterogeneous have overcome problems facing system. Of these, magnetic nanomaterials magnetite spinel ferrites introduced. A literature survey comprehended review concerning nanocatalysts, preparation methods, applications. economic lookout portrayed using future vision. Besides, biodiesel's physicochemical properties kinematic viscosity, density, cetane number, flash, pour, cloud points reviewed commercial utilization.

Abstract Most of the household relies on an LPG cooking stove for meal preparation, with approximately 20 crore families across India consuming 1.5 lakh crores annually. Due to their dependency open areas, present solar cookers are useless at night and morning, restricting usage afternoon despite sufficient radiation 9–10 months. Phase-change materials expensive thermal energy storage (TES) devices needed conventional power facilities. An economical TES system using parabolic sun dish collectors is decrease import costs pollution. In response, this project aims design a collector coupled system, utilizing specially engineered carbon bricks enhance heat retrieval capacities while reducing initial costs. Employing ANSYS-CFX software, undergoes thorough examination. Computational fluid dynamics analysis conducted evaluate transfer coefficients both hot fluid, responsible heating bricks, cold which cools them. The results reveal ranging from 15 W/m2 K 25 40 latter demonstrating higher attributed air’s density compared fluid’s lower density. Overall, exhibits estimated coefficient 20–25 K, facilitating efficient recovery heat.
