Abstract : The Analytical Diffusion Model (ADM) program has been written to predict the performance of continuous wave (cw) HF or DF chemical lasers. ADM performs laminar and turbulent calculations for slit or axisymmetric nozzles. It is based upon a temperature-dependent analytical solution for the premixed case coupled with a flame sheet mixing scheme, and can be run under either constant pressure or constant density conditions. The ADM program is ideal for parametric studies because of its minimal computer run time and is able to reproduce the results of the numerical cw chemical laser programs consistently to within a few percent.
