N2 - The fluctuating field of a jet excited by transient mass injection is simulated numerically. The model is developed by expanding the state vector as a mean state plus a fluctuating state. Non-linear terms are not neglected, and the effect of non-linearity is studied. A high order numerical method is used to compute the solution. The results show a significant spectral broadening in the flow field due to the non-linearity. In addition, large scale structures are broken down into smaller scales.
