摘要: A numerical study was carried out to examine the development of duct flows being affected by combined buoyancy force-driven secondary flow and mass transfer. The developing heat transfer have been simulated numerically for a horizontal fuel cell with rectangular trapezoidal cross section. Constant flux rate are prescribed on bottom wall, while thermal insulation is implemented other three impermeable walls. buoyancy-generated can disrupt hydrodynamic boundary layers, thus affect friction factor Nusselt number. Calculations performed determine effects various Grashof number, rate, Reynolds Comparisons these results available data presented.
