Default Sun Movement

Posts: n/a
I am cuurent trying to determine a satifactory way of modelling the movement of the sun and how to setup the sun in CFD modeling.

As part of the above sun movement, I am also trying to detrmine how to set abmient temperatures as a function of time.

Does anyone know of a phoenics journal or like on this topic, I have searched their web site, but nothing like this stands out. As I need to purchase the journal I need to be confident that the contents will be useful.

Any help would be greatly appreciated.

Thayou in advance for your time.

we do calculations of coolant plumes from power plants discharging into coastal waters. We use an in-house developed code for calculating the sun's height and thus the solar radiation reaching the water surface (as well as other ocean-atmosphere heat exchange processes). Being old-fashioned PHOENICS users we've coded everything in separate Fortran subroutines in GROUND.

If this sounds like what you're looking for, drop me an email and we can discuss it more thoroughly. You are also welcome to the algorithms we use.
