This paper presents a design for a novel, palm sized, high-aspect-ratio engine. To simplify fabrication and keep the device unobtrusive, a design incorporating a two-cycle engine having a flat, rectangular piston with spring return was selected. An e

In a previous paper, a model was developed for the nonlinear acoustic resistance for compact insertion elements. Within the model, two loss coefficients are used to tune the model for each type of element, and data were used to empirically determine

Normal shocks are generally treated by defining a stationary adiabatic shock discontinuity with a supersonic upstream velocity. A fundamental feature of this approach is that the problem is steady, and the stagnation enthalpy is constant across the s

In a previously published paper, a model for the nonlinear acoustic response of an area contraction including bias flow was presented. The model's prediction for the zero-driving resistance grew progressively worse as the steady-flow Mach number incr

The ability of acoustic network models to model combustion instabilities is dependent on the accuracy of acoustic two-port models. While several forms of two-ports are available, the most common for these types of analyses is the scattering matrix. T

Acoustic instabilities are frequently the culprit for engine failure. To mitigate these instabilities, an accurate model of the nonlinear acoustic pressure profile of the system is necessary. This study develops a nonlinear model for the acoustic res
