Abstract
Taking the air flow conjugated heat transfer of narrow rectangular channels with the conjugate heat conductivity column as an example, a kind of CFD simulation technology is introduced in this paper. First, Pro/e 5. 0 is used to establish a heat transfer model, Then, imported it into ICEM CFD meshing. At last, solved and calculated it in CFX. The temperature, velocity and pressure profile of the different section were obtained through the simulation of the whole heat transfer process, meanwhile the flow and heat transfer are compared and analyzed in the case of different height to width ratio in narrow rectangular channels, obtained that rectangular channels corner of large width to height ratio appeared flux concentration phenomenon near up-down plane regional, and with height to width ratio greater, export air temperature higher, the heat transfer effect better, but the resistance is greater, the pressure drop is higher.关键词
