Abstract

In recent times, solar energy has attracted the attention of scientists to a large extent. On the surface, there are two reasons for this: first, scientists interested in this with the intention of innovating new functions and, secondly, to develop new ways to capitalize on it. The parabolic solar collector is a widely used concentrated type solar collector that contains a parabolic reflector and a plate or absorption tube in which the working fluid circulates. The basic function of the parabolic reflector is to concentrate the solar radiation and reflect it in the absorbent tube. The overall efficiency of the energy or collector generation system depends on the intensity of solar radiation, the shape and design of the collector, the design and the material used to absorb and characteristics of the working fluid, as compared to thermoelectric properties. Device miniaturization and energy efficiency are the main areas of interest around which new materials are developed. The design of the solar system can make some basic changes if the new materials are successfully applied. However, nano-fluids are a relatively new innovation with better heat absorption and heat transfer capacity. In this research, CuO and alumina, nano fluids are used instead of water as a working fluid. The research was conducted on three periods of 10h, 13h and 16h. When the water is replaced with 0.01% nano-liquid CuO / H2O, the outlet temperature increases by 45.5% compared to water at 10 h, 25% at 13 h and 50% at 16 h, against 0, 05% nano. CuO / H2O fluid is used that increase the temperature increases to 63.6% at 10 hours, 71.4% at 13 hours and 70% in 16 hours. The results, we can say that the increase present in 0.05% CuO / Nano water fluid is greater, this is due to the better the thermal properties of copper to conduct heat. In this research, the efficiency of the parabolic solar collector with nano fluids is tested to determine the position of Bhopal (M.P.).
