In the nondimensional turbulence intensity range from 1 to 15, it was found that the mean fractal dimension is about 2.2 and it does not show any dependence on turbulence intensity.
The results show that the turbulent burning velocity is predominantly influenced by the featureless background turbulence over the range of parameters considered, although there is approximately a 4 7% increase in the flame speed that results from the presence of structures.
The need to simulate fully developed turbulence with wide range of scales led us to use the Piecewise Parabolic Method (PPM) to solve the Euler equations of motions.
It is a reflection of an influence of the temporal changes of the structure of the interplanetary magnetic field (IMF) turbulence in different range of frequency f during Fd.
In order to capture key features of engine spray-combustion environments, the LEM methodology is extended by introducing a conical LEM domain to approximate spray spatial development, fuel vapor input based on CFD-prescribed spray evaporation, and a representation of large scale turbulent motions distinct from the inertial-range turbulence that develops at smaller scales.
The newly proposed combustion scheme can reasonably describe the interaction of chemistry and turbulent flow over a wider range of turbulence conditions.
Combustion and Flame 18, 133 153) by means of which the relation between turbulent burning velocity and turbulence intensity in the range of 1 m/s
In general, it appears to be practical to use representative pseudo-turbulent PDF and SDR models for a range of turbulence intensities and length scales.
Secondly, we check the capabilities of the nesting procedure to facilitate regeneration of the inertial-range turbulence structure by the small-scale LES.
Atmospheric boundary layer (ABL) turbulence, with intensities ranging from 13%to27%7% and integral length scales from 6 to 13 times the building height, is simulated in a boundary layer wind tunnel.
A turbulent burning velocity was determined for a range of turbulence velocities and equivalence ratios.
