Simulation of solar thermal power heat exchanger

Abstract

The research project addresses the increasing demand for sustainable energy by optimizing heat exchanger efficiency in solar thermal power systems. By examining key variables like material selection, flow rates, configurations, and intake temperatures, the study fills gaps in the current literature. Using a detailed 3D model and simulations, it provides insights into heat exchanger operation. Emphasizing technical progress, energy efficiency, cost containment, and environmental sustainability, the solar energy trough collector methodology prioritizes durable and cost-effective materials. Practical considerations lead to the selection of mirror-coated aluminum over silver for reflecting surfaces and mild steel for structural components. Copper tubes are chosen for the collector's design due to advantageous mass flow rates and heat transfer properties. The completed parabolic trough collector design, incorporating a rotating mechanism for heat management, demonstrates practicality in both construction and functionality. The study extends to solar thermal energy storage systems, covering design standards, material selection, and emerging technologies. It explores three types of solar thermal storage materials, considering specific heat, fusion heat, and heat requirements in the design of a storage tank. ANSYS Workbench simulations and mathematical models are presented, concluding with discussions on the parabolic trough's length, heat calculations, and a recommendation for water-based coolant over ethylene glycol. The research suggests future exploration of fluid dynamics and heat transmission in parabolic collectors at varying temperatures.
