Abstract

The determination of radiation view factors from a differential strip to a rectangular plate to other finite geometries, has practical importance in many engineering applications. Examples are radiation exchange within the internal engine cavities of gas turbines, furnaces, kilns, reactors, and other devices that normally operate at high temperatures. To date, the general analytical expression for view factor from a rectangular plate with an arbitrary orientation and dimensions has not been available. This study attempts to develop an exact and general formula for shape factors: (1) from a differential element to an arbitrary nonintersecting finite rectangular plate, and (2) from a differential strip to a rectangular plate with the former being in a plane that has parallel generating lines to the latter, This formula is then used to generate the view factors from a rectangular plate to some finite geometries via single integration.
