摘要: A turbulent diffusion flame adjacent to a solid fuel in parallel airflow is studied analytically. The flow assumed be of boundary-layer type where the mean properties flowfield are predicted by low-Reynolds-number K-epsilon two-equation model. chemical reaction approximated as one-step and infinite-fast. mass-fraction distribution boundary layer described pdf. Four kinds pdf used: beta, clipped Gaussian, double delta, ten-point respectively. general features each structure obtained applying corresponding quite similar. velocity, mixture fraction temperature profiles appear nearly identical uses beta Gaussian 25 refs.
