The effects of vent opening size, vent axial location and number of vents on the combined natural convection-radiation cooling of a one-side uniformly heated vertical channel data in air Computational for temperature, streamwise are mass and numerically flow rate, transverse investigated. heated velocity wall and temperature profiles and air bulk temperatures are presented for various vent configurations. For vented channels the heated wall temperature is shown to increase above the corresponding unvented channel temperatures through the region upstream of the farthest from the bottom vent location. For a single low positioned vent, the vented wall temperatures are lower than corresponding unvented channel temperatures for only a portion of the wall downstream of the vent location. For a continuously heated wall, in general, vents are found to deteriorate the overall cooling process.
