WebJan 31, 2024 · The heat transfer of methane at supercritical pressure in a helically coiled tube was numerically investigated using the Reynolds Stress Model under constant wall temperature. The effects of mass flux ( G ), inlet pressure ( Pin) and buoyancy force on the heat transfer behaviors were discussed in detail. WebConsider the combustion of Methane. CH4 + 2O2= CO2 + 2H2O Since the volumetric content of each gas is in the same ratio as the kmol fractions then volumetric content is in the same proportion as the molecules. Hence it needs 2 volumes of oxygen to burn 1 volume of methane. The volume of air needed is 2/21% = 9.52 volumes. matte white tile trim
