“…Many salient features of the present kinetic theory approach to chemically reacting flows have been revealed previously (Bywater, 1982;Chung, 1967;1970;1973;Hong, 1975;Hong and Chuang, 1988). The flame zone…”

“…In Bywater's work, the cross correlations or high order moments were not shown in his results. The same kinetic theory was employed by Hong and Chuang (1988) to solve the twin plane jets turbulent mixing by using the modified Green's function method. The cross correlations of the fluctuations were described via the revealed joint pdf, f (u′,v′), in Hong and Chuang's (1988) work.…”

A turbulent kinetic theory due to Chung and a Green's function method by Hong were employed to solve a reacting turbulent plane jet problem. An instantaneous mixing concept was used to simulate the steady state of turbulent plane jet with combustion. The probability density function description of the fluid elements in a turbulent reacting flow could properly explain the turbulent flame zone structure and the turbulent transport of heat, momentum and chemical species even under the infinitely fast reaction rate assumption. The calculated distributions of the various moments of the turbulent combustion field were found in good agreement with the available experimental data. The dynamic behaviour of combustion in the turbulent field could be better understood via the probability density function description of the present turbulent kinetic theory approach

“…In addition, the decay of the maximum velocity of the twin jets is consistent with that for a single jet, when a high Reynolds number flow issues from two nozzles that are separated by a large spacing. Hong and Chaung (1987) reported the solution for twin plane jets using a kinetic theory approach (constructing a probability density function via integration of a Green's function over the source distributions according to the boundary conditions) without turbulent transport coefficients or eddy viscosity. The mixing mechanism, Reynolds stress and turbulent energies (second-order correlations of turbulent transport phenomena) were predicted using this approach.…”

Turbulent mixing of a single jet, twin jets, triple jets and multiple jets is synthetically analysed in this paper. Chung's kinetic theory of turbulence and a modified Green's function are employed to solve this problem. The probability density function of fluid elements in the velocity space of multiple plane jets and the corresponding turbulence correlations are revealed in this analysis. The calculated results are found to be in good agreement with the available experimental data. The internal physical structure of the turbulent mixing mechanism seems better understood via the kinetic theory approach. The present study provides the fundamentals for theoretical understanding of multiple-jet turbulent mixing and further application to multiple-jet turbulent combustion analysis. KEY WORDS
