Help on Solar heating on roof
Hi all, i am embarking on a project where i require some assistance on CFD-Fluent as i am a begineer on it.
Description of project: -To draw a 1D rectangle block to simulate as a building with an additional small rectangle on top of it to simulate as a cool paint coated on the roof top. -The block is subjected to solar radiation heating over a period of 365 days -Due to the cool paint coated on the roof top, there is an increase in reflectivity and emissivity that reduces the temperature on the roof surface -this also lead to an reduction of surrounding temperature Objectives of project: 1) To find out the (average) temperature distribution of up to 10m from the surface of the roof for a period of 365 days 2) To find out the (average) temperature on the coated paint surface for a period of 365 days 3) To find out the (average) temperature on the surace of the roof below the coated paint surface. -To draw a 1D rectangle block to simulate as a building with a thin layer of cool paint coated on the roof top. HELP needed: 1) How do i set up a model where i can set up a boundary area where the space up to 10m from my roof surface are considered as part of my model. What software should i use to draw the model before i import to Fluent? 2) How do i input in the emissivity and reflectivity values of the coated roof surface into Fluent? 3) I understand that there is a solar loading tab in Fluent for a particular day and time. However, how do i set it such that it tabulates for a period of 365 days and obtain the average values? Any help is greatly appreciated.
