Gas transfer velocity
WebA non-dimensional formula (hereafter the RHM model) is proposed in which gas transfer velocity is expressed as a main function of wave Reynolds number (RHM = UwHs/νw, where Uw is wave orbital velocity, Hs is significant wave height, νwis viscosity of water) while wind is accounted as an enhancement factor (1+Û, where Û is non-dimensional … WebExemplary embodiments provide charging systems and methods for effectively delivering charges onto a receptor. The charging system can include a low velocity gas stream, an emitter assembly for providing cathode-to-anode field bias to generate charges from the low velocity gas stream, and an emitter-to-receptor (e.g., photoreceptor) electric bias to …
