【 摘 要 】

The thermal discharge from power plants adversely affects its surrounding ecological environment, so it is of practical significance to study the diffusion characteristics of the thermal discharge as the global ecological environment problem becomes more and more serious. The change of the temperature and velocity of the buoyant jet with different inclination in the co-current environment were studied. The main conclusions are as follows: the jet velocity and temperature decay rapidly near the orifice, and the region with the largest change of velocity is also the region with the greatest dilution of temperature. The influence range is mainly within 80 times diameter of the nozzle. The smaller the jet angle is, the slower the change of velocity and temperature decay.
