A COMPARATIVE STUDY ON HEAT TRANSFER NANOFLUID FOR SOLAR PARABOLIC TROUGH COLLECTOR

In present state of limited resource of fossil fuels which are polluting in nature need to utilize nonconventional energy source like solar energy. Solar energy is globally available but it is disseminated in nature, solar concentrator like Parabolic through is widely used for industrialized process heat and power plant application using day time sunshine at almost no operating cost. Efficiency of collector depends on many parameter and input. One of the important parameter is type of heat transfer fluid and mass flow rate of it. Many researchers have done analysis and experimentation for various fluids for enhancement of heat transfer of absorber tube, here attempt is to have comparative study of different fluid with and without nano particle recommended by numerous investigators and it is reviewed for its proposed application for increasing efficiency and effectiveness of solar parabolic trough collector.
