摘要
以油田规模化利用太阳能为背景,建立基于蒙特卡洛射线踪迹法的腔式吸热器光热转换物理模型和数学模型,通过数值模拟计算腔式吸热器的热流密度分布特性,设计一种新型太阳能腔式吸热器,结合油田应用对太阳能腔式吸热器出口水温进行计算.结果表明,新型太阳能腔式吸热器的热流密度分布基本呈正态分布,在太阳辐射强度为1 100W/m2,最大辐射热流为0.22MW/m2时,系统实际聚光比为200,吸热器出口水温为50.2℃,能够满足油田应用需求.
Utilizing solar energy in oilfield has a strong industrial background and industry needs,and performance of the solar cavity/receiver is the key factor of using solar in the form of big-scale and low-cost.This paper aims to design a new-type solar cavity/receiver and simulate the heat flux inside the solar receiver based on Monte-Carlo ray-tracing method,then calculate fluid temperature in the outlet of the receiver.The computer code for Monte-Carlo ray-tracing method was written in FORTRAN language in-house.The results show that fluid temperature in the outlet is 50.2 ℃,which can meet the engineering application.The results also show that the highest radiation flux is 0.22 MW/m2 when the incident solar irradiation value is 1 100 W/m2,and the concentration ratio of the system is 200.This can serve as a reference for the future utilizing solar energy in oilfields.
