Abstract

An experimental study was conducted to investigate the velocity characteristics of inclined gravity plumes. Two slope angles, 20 and 40 degrees, were examined. The velocity measurements were performed with Digital Particle Image Velocimetry through a proper matching of the refractive index of the effluent and the ambient water. The simulations were conducted in an inverted manner to reduce the amount of ethanol required for the refractive index matching. Results show that the centerline U-velocity profiles in the free mixing region follows a similarity curve after approximately 30d. The normal spreading of the plume increase when the slope increases. On the other hand, a wider lateral spread occurs when the sloping angle decreases.
