This paper presents a spectral wave action model to simulate random wave deformation and transformation. The wave model is based on the wave action balance equation and can simulate wave fields by accounting for wave breaking, shoaling, refraction, diffraction and wind effect in coastal waters. It is a finite-difference, phase averaged model for the steady-state wave spectral transformation. The wave model is applied to verify different experimental cases and real life case of considering the several factor effects. The calculated results agree with the experimental and field data. The results show that the wave model presented herein should be useful in simulating the wave transformation processes in complicated coastal waters.
A detailed reaction mechanism is adopted to simulate n-heptane laminar premixed flame in this paper. The reaction mechanism comprises 108 components and 572 elementary reactions. The main reactants (O2,n-C7H16), reaction products (CO2,CO,H2,H2O), intermediate products (CH4, C2H4, C2H2, C3Hx) and the concentration distribution of PAHs in the flame are analyzed in the numerical method. The numerical results are in good agreement with the experimental results, which states that the mechanism can predict PAHs in the n-heptane flame. In this paper, the sensitivity and reaction flow analysis method is used to analyze the numerical results and the PAHs formation routes in n-heptane laminar flow premixed flame are obtained.
