“…The lines are labeled with the values of salinity (in g · kg −1 ) for which they were generated estimate the uncertainty of their measurements at 1.06 %, the deviations between their data and those of Caldwell [33] are higher and are 2 %. Figure 7 compares the predictions with the data of Jamieson and Tudhope [35], which, unlike the other seawater data, cover a rather wide range of salinity and temperature. Jamieson and Tudhope [35] reported a matrix of experimental data for salinities from 33.57 g · kg −1 to 153.46 g · kg −1 in the temperature range from 273.15 K to 348.15 K and an additional series of measurements for salinities of 153.46 g · kg −1 up to 448.15 K. Based on these data, they developed a set of smoothed values, which are shown in Fig.…”

“…The data are available from multiple sources [33][34][35][36][37][38] and span a reasonably wide range of pressures (up to 1400 bar), temperatures (from 273.15 K to 453.15 K), and salinities (up to 153.46 g · kg −1 ). For the calculation of the thermal conductivity of seawater, the reference seawater composition [39] was used.…”

A model has been established for calculating the thermal conductivity of aqueous electrolyte solutions containing the Na + , K + , Mg 2+ , Ca 2+ , Cl − , SO 4 2− , CO 3 2− , HCO 3 − , and Br − ions. The model is based on a previously developed computational framework for the thermal conductivity of mixed-solvent electrolyte systems, which has been expanded by explicitly accounting for pressure effects in addition to temperature and electrolyte composition effects. The model consists of a contribution of the solvent, a contribution of individual species expressed using modified Riedel coefficients, and an ionic strength-dependent term that is due to interactions between species. The model accurately represents the thermal conductivity of solutions containing single and multiple salts at temperatures ranging from 273 K to 573 K, pressures up to at least 1400 bar, and concentrations up to the limit of solid saturation. Further, the model has been applied to seawater and used to elucidate the discrepancies between the experimental data for seawater and those for Na-K-Mg-Ca-Cl-SO 4 salt solutions. With parameters evaluated on the basis of data for binary and multicomponent salt solutions, the model provides reliable predictions of the thermal conductivity of seawater.

“…Since concrete is a compound of many materials, thus, its thermal properties is computed based on the volumetric fraction and the thermal properties of those compound materials respectively [1]. Table 1 shows the thermal properties of materials [2][3][4][5][6]. According to Neville [7], the specific heat of concrete has little effect by the mineralogical character of aggregate, but mainly depend on the amount of moisture content.…”

ABSTRACT:The thermal properties of cement-based materials have gained more attention not only for the thermal analysis but also for the application of Non-Destructive Tests for building, bridge and other structures. Presence of chloride ions in pore structure was also found to affect thermal properties of concrete. This paper aims to study effects of chloride content on thermal properties of concrete. Specimens were submerged in sodium chloride solution for different period of time. Then, they were subjected to the heating test. It was found out that temperature of specimens with presence of chloride ions in pore solution increased faster compared to specimens without chloride contaminations. As the amount of chloride content in pore structure increased, concrete temperature also rose faster. The results obtained from this study can be used to accurately estimate thermal properties of concrete so that thermal analysis and application of Non-Destructive Tests such as Infrared Thermography can be effectively implemented.

Seawater cooling towers have been used since the 1970's in power generation and other industries, so as to reduce the consumption of freshwater. The salts in seawater are known to create a number of operational problems including salt deposition, packing blockage, corrosion, and certain environmental impacts from salt drift and blowdown return. In addition, the salinity of seawater affects the thermophysical properties which govern the thermal performance of cooling towers, including vapor pressure, density, specific heat, viscosity, thermal conductivity and surface tension. In this paper, the thermal performance of seawater cooling towers is investigated using a detailed model of a counterflow wet cooling tower. The model takes into consideration the coupled heat and mass transfer processes and does not make any of the conventional Merkel approximations. In addition, the model incorporates the most up-to-date seawater properties in the literature. The model governing equations are solved numerically and its validity is checked against the available data in the literature. Based on the results of the model, a correction factor that characterizes the degradation of the cooling tower effectiveness as a function of seawater salinity and temperature approach is presented for performance evaluation purposes.
