| 中文摘要: |
| 我国西部高原地区分布着大量的太阳能电池板,而高原地区的低气压会导致材料燃烧与常压环境下存在差异。在五种外加热辐射热流条件下,研究了气压变化对背板引燃的太阳能电池板点火时间、质量损失及火焰高度等特性参数的影响规律。结果表明,太阳能电池板的点燃时间与气压呈负相关;质量损失速率、火焰高度随气压的增加而增加,拟合实验数据后发现不同的辐射热流下质量损失速率均与气压近似呈线性关系;基于质量损失率与气压的关系,在前人公式基础上推导出太阳能电池板火焰高度与气压的指数关系,对比实验拟合数据符合良好。 |
| 英文摘要: |
| A large number of solar panels are distributed in the western plateau region of China, where the low pressure leads to a distinct combustion process compared to a normal pressure environment. This paper investigates the influence of air pressure on the combustion characteristics of solar panels ignited from the backboard under five external heat fluxes, including ignition time, mass loss, and flame height. The results show that the ignition time of solar panels is negatively correlated with air pressure. Thermal response parameters at different air pressures are calculated from the relationship between ignition time and external heat flux. The mass loss rate and flame height increase with the increase in air pressure. After fitting the experimental data, it is found that the mass loss rates are linearly related to air pressure across different heat fluxes. Subsequently, based on the relationship between mass loss rate and air pressure, an exponential relationship between the flame height of solar panels and air pressure is derived from previous formulas and fits well with experimental data. |
