Hello,
Is it true that we cannot suppose a "beta" deistribution of temperature, mixture fraction and density (in non premixed combustion)WHEN THE PRESSURE IS HIGH ( 40 to 100 bars) ??? the results in moderate pressures 1,2,3 bars are acceptable when using prepdf, but they did not in high pressures. what's the problem ??? is it due to the use of stochastic distribution, or the "presumed" shape is not well (perhaps I should use a calculated pdf ?). thanks |
