Abstract

Plain orifice, or “pressure atomizers” are the most commonly used atomizers due primarily to their simplicity and ease of manufacture. This chapter provides background on the characteristics of these devices in terms of spray production and general behavior. Classical linear theories are reviewed to provide a basis for theoretical droplet size predictions. More recent developments assessing the unsteadiness within these devices, and its role in spray production, is also provided in subsequent discussion. The chapter closes with modern nonlinear simulations of spray production using modern numerical techniques.
