Abstract
The objective of this thesis is to study the effect of nanoparticles additives suspension to molten salt as a base fluid on the design of a solar thermal power plant using parabolic trough collector technology. The collected solar energy is used to drive a Power block based on Rankine cycle. One of the main features of this system is storing energy in a thermal energy storage tanks which provides the system by energy stored at night hours. Molten salt is the heat transfer fluid used in solar parabolic trough collectors and thermal energy storage tanks. A mathematical model using engineering equation solver (EES) is used to determine the thermo-physical properties i.e. specific heat, density and viscosity have relations with the nano-particles volumetric concentration. The effect of varying nano-particles volumetric concentrations on the design of solar thermal power plant with energy storage tank at mean fluid temperature, changing the geometric dimensions of the components of solar field like number of parabolic trough collector modules, the mass flow rate of the heat transfer fluid also dimensions of the energy storage tank, more over the over-all plant efficiency; Nanoparticles used are Aluminium oxide (Al2O3) and Copper (Cu). The results showed that specific heat capacity has an inverse relation with nanoparticles volumetric concentration.
