Basic Concepts Basic Concepts Enclosures consist of two or more surfaces that envelop a region of space (typically gas-filled) and between which there is radiation transfer. A nonparticipating medium within the enclosure neither emits, absorbs, nor scatters radiation and hence has no effect on radiation exchange between the surfaces. Each surface of the enclosure is assumed to be isothermal , opaque , diffuse and gray , and to be characterized by uniform radiosity and irradiation . Virtual , as well as real, surfaces may be introduced to form an enclosure.
View Factor Integral The View Factor (also Configuration or Shape Factor) The view factor, Fij is a geometrical quantity corresponding to the fraction of the radiation leaving surface i that is intercepted by surface j . . ij F Consider exchange between differential areas i : j dA and dA

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
