DOI: 10.1063/5.0260587
Abstract: This research explores the flow dynamics and heat transfer characteristics of asymmetric (elliptical orifice) and symmetric (circular orifice) synthetic jets (SJ). The present investigation clearly distinguishes axis-switching phenomena responsible for variation in heat transfer rate… read more here.
