Study on Multi-Port Disposal of Thermal Wastewater in Co-Flowing

Water environmental pollution is a widely attended important problem. With the development of economy and improvement of living standard, the discharge quantity of city sewage, power plant cooling water, etc. is increasing gradually. Because the discharge process is concerned with jet behavior, so it is significant to study on flow behavior near discharge outlet of sewage treated building in the theory research and practical apply. With reference to the model of RSM, Buoyant jet of thermal water in co-flowing was simulated. The velocity and temperature field, buoyant jet trajectory, temperature attenuation along the axis, buoyant jet trajectory impacted by buoyancy force of different velocity ratio and different jet temperature are briefly discussed.Furthermore, this study revealed the major factor which impact attenuation of velocity and temperature.
