摘要

摘要:本文提出了常压(101.3 kPa)下浅水水环境中水密度与其温度和盐度之间的温盐状态方程(EOS)。海水具有标准的海洋离子组成。拟议的EOS适用于寒冷、温带和炎热气候下的淡水、半咸水、咸水、高咸水和盐水环境。水的密度被认为与温度成非线性关系，而与盐度成线性关系。这一假设对于实际应用是足够的- -允许将EOS转换为有关的密度差方程- -用于计算内陆、河口、沿海和海洋水域的热流和热盐流模型中的密度差和浮力。

Thermohaline equation of state for pure water, seawater and brine

ABSTRACT A thermohaline equation of state (EOS), relating the density of water to its temperature and salinity, is proposed for shallow water hydro-environment applications, at normal atmospheric pressure (101.3 kPa). The seawater is of standard ocean ionic composition. The proposed EOS applies to fresh, brackish, saline, hypersaline and brine water environments, in cold, temperate and hot climates. The density of water is considered nonlinear with temperature, but linear with salinity. This assumption is adequate for practical applications – allowing the transformation of the EOS into a relevant density difference equation – for calculating density differences and buoyancy in models of thermal and thermohaline flows in inland, estuarine, coastal and ocean waters.

期刊介绍： The Journal of Hydraulic Research (JHR) is the flagship journal of the International Association for Hydro-Environment Engineering and Research (IAHR). It publishes research papers in theoretical, experimental and computational hydraulics and fluid mechanics, particularly relating to rivers, lakes, estuaries, coasts, constructed waterways, and some internal flows such as pipe flows. To reflect current tendencies in water research, outcomes of interdisciplinary hydro-environment studies with a strong fluid mechanical component are especially invited. Although the preference is given to the fundamental issues, the papers focusing on important unconventional or emerging applications of broad interest are also welcome.
