ok, thanks for all the help I hope I made it, I will appriciate if you can give me a feedback on my work
so here a picture of the conteiner and a object (for example engine) that prouduce heat flux (section view)
so as we can see in the left side, the boundry condition i make are:
- fixed temperutre - of 25[c] of the earth the contiener seat on (like in the video you send me of the fire)
- Â convection - on the all wales (not enclud the floor) with value of film coefficent = 50W/m^2C while temp is 35[c] this from the wind
- Heat flux - I didnt saw the option of radiation from the sun so I saw a viedo that says that the approximate heat flux that can replace the radiation is 1000 W/m^2 so i put it on the top of the conteiner (I decided that the sun is in the middle of the sky)
- Heat flux 2 - an approximate heat flux from the object (engine or what else) of 400 W/m^2
- convection 2 - the holes (rectungular holes) in the walls are not forced convention so I put 35[c] and film coefficent = 10W/m^2CÂ the convection is on the wall of the engine like in the pic
- convection 3 - the 1 hole in the walls are forced convention (ventilator) so I put 35[c] and film coefficent = 50W/m^2C the convection is on the wall of the engine like in the pic        here image without no section view  Â
tThanks very much
