The Use of TATR (Total Amount of Temperature Rise) Index in Numerical Simulation of Xiangshan Bay's Temperature Rise

Abstract:

It is a key problem that when the temperature rise in seawater reaches balance under plants' thermal discharge. In the process of numerical simulation of Xiangshan Bay's temperature rise from plants' thermal discharge, TATR (Total Amount of Temperature Rise) was introduced as an index to help find the balance time. TATR shows its advantages of stability and reliability when compared with other indices such as volume. With TATR, it was found that the temperature rise reaches balance after 80 days' thermal discharge in winter while it takes 70 days in summer. Under thermal discharge of two plants, TATR at balance time is 1.77 (10⁹m³°C) in winter and 2.82 in summer. Under discharge of only Guohua Plant, it is 0.60 in winter and 1.56 in summer. Under discharge of only Wushashan Plant, it is 1.16 and 1.37 respectively. Based on the correct balance time, the temperature rise in nearby waters due to two major plants' thermal discharge was calculated, which provided useful data for researches such as water-environmental value loss.
