Abstract: According to the theory of computational fluid dynamics and numerical heat transfer, the mathematics model of multi-hole horizontal heated water discharge is established and solved with numerical analysis by finite volume method. The temperature distribution of multi-hole heated water path is calculated and obtained with numerical methods. The effect of number of holes and relative hole spacing on the temperature distribution of heated water path are analyzed. Results indicate that under the same heated water discharge, the same discharge temperature, and the same hole velocity, one-hole discharge or reducing hole spacing will enhance the thermal diffusion of heated water path, and can decrease thermal pollution on the environment effectively.
