研究目的
To present a detailed mathematical model of the Parabolic Trough Collector (PTC) receiver for controlling the fluid temperature as well as the absorber and the glass cover temperatures.
研究成果
The study presents a mathematical model of the PTC receiver capable of predicting the system's temperature response based on input variables like inlet temperature, heat transfer fluid flow rate, ambient temperature, wind speed, and solar illumination. Future work includes simulation and control of solar stations with PTC receivers.
研究不足
The study is theoretical and does not include experimental validation. The model assumes several simplifications such as incompressible heat transfer fluid, symmetrical parabola shape, uniform ambient temperature, and negligible temporal variations in temperature in the thickness of the absorber and glass.
1：Experimental Design and Method Selection:
The study involves the theoretical modeling of the PTC receiver, focusing on the thermal exchanges within the system. The model is based on the description of various thermal exchanges occurring in the system, assuming axial symmetry.
2：Sample Selection and Data Sources:
The study does not specify sample selection or data sources as it is a theoretical model.
3：List of Experimental Equipment and Materials:
The study mentions a circular tube absorber with a selective layer and a glass cover but does not specify brands or models.
4：Experimental Procedures and Operational Workflow:
The study outlines the thermal balance equations for the absorber tube, the glass envelope, and the environment, considering forced convection and radiation.
5：Data Analysis Methods:
The study uses mathematical modeling and finite differences method to analyze the thermal behavior of the PTC receiver.
