Hello, I use Solar Calculator today to compute solar irradiation.
But I find that different version(ansys fluent 14.5 and fluent 6.3.26) gives me different results. Fluent Version 6.3.26 Fair Weather Conditions: Sun Direction Vector: X: -0.468382, Y: -0.19428, Z: 0.861901 Sunshine Fraction: 1 Direct Normal Solar Irradiation (at Earth's surface) [W/m^2]: 854.507 Diffuse Solar Irradiation - vertical surface: [W/m^2]: 134.182 Diffuse Solar Irradiation - horizontal surface [W/m^2]: 115.757 Ground Reflected Solar Irradiation - vertical surface [W/m^2]: 85.2258 Fluent Version 14.5 Fair Weather Conditions: Sun Direction Vector: X: -0.468382, Y: -0.19428, Z: 0.861901 Sunshine Fraction: 1 Direct Normal Solar Irradiation (at Earth's surface) [W/m^2]: 855.955 Diffuse Solar Irradiation - vertical surface: [W/m^2]: 98.3146 Diffuse Solar Irradiation - horizontal surface [W/m^2]: 115.383 Ground Reflected Solar Irradiation - vertical surface [W/m^2]: 85.3132 Most of the value are the same, but Diffuse Solar Irradiation - vertical surface is totally different, I am confused about this. And I don't know which one is right, so I could not continue the simulation. Can anyone help me? Thank you in advanced. |
