✦ Synopsis

Many researchers have modeled ideal mixing and entrainment phenomena using control volume methods. The simplicity, robustness and generally useful results make this one dimensional (1D), quasi-1D approach a viable and attractive methodology, especially for preliminary design work. However, to extend modeling capability beyond simple ideal mixing models remains a challenge. This is even more the case when we limit the extension to analytically based expressions with a minimum of empirical information. Here, we develop a family of models that extend to include non-ideal eects such as skin friction. Comparison to available aerodynamic nozzle data is presented to illustrate the viability of these methodologies.
