I've made a model of a parabolic mirror and a receiver located at the focal point, to simulate radiation concentration on the receiver. i've defined these conditions:
* in "general settings", solar radiation direction along the axis of symmetry of the parabolic mirror (0,-1,0), intensity:1000W/m^2
*whitebody condition on the mirror surface and blackbody condition for the receiver.
* blackbody walls in simulation wizard window
*goal: net radiation flux, average value
*I've tried multiple result plots, non show an increased radiation intensity, of more than 1000W/m^2 on the side of the receiver that faces the mirror.
This is the first time I'm setting up a thermal or radiation analysis, so there must be something wrong with my problem definition and settings. Please help.
I attached the files.(solidworks 2013)
can you elaborate on what plots you're using and what value you're plotting?
also, have you done an energy balance? I noticed that your model has a very very coarse mesh. You may have asked for 1000 but you should check that you're actually getting 1000 on the face.
I would also start with everything being black bodies and then later on tune the model with other surface radiation properties like white body.
