Effect Of Orifice Shape On Synthetic Jet Efficiency, David J. Nani
Effect Of Orifice Shape On Synthetic Jet Efficiency, David J. Nani
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
A synthetic jet is formed by periodic oscillation of a fluid through an orifice. The oscillatory motion is driven by diaphragm or other driver. Previous studies have demonstrated that synthetic jet formation and time-averaged cavity pressure are a function of the orifice shape. Traditionally, the performance of the jet is evaluated with varying configurations of fixed driver input voltage or fixed driver displacement. Neither of these measures accurately reflect the efficiency of the actuator. Defining efficiency as "desired output divided by required input," these traditional measures may not account for increase in required driving current or force.
