The equations for calculation of the average coefficients of heat emission and mass exchange in regular and irregular beds with different contact elements, as well as the expression for calculation of the average turbulent exchange coefficient are presented. The given formulas determine these coefficients...
Thermal performance analysis of heat exchanger for closed wet cooling tower using heat and mass transfer analogy In closed wet cooling towers, the heat transfer between the air and external tube surfaces can be composed of the sensible heat transfer and the latent hea... SY Yoo,JH Kim,KH Han...
This paper developed XJCT-3D, a simulation software for cooling tower wet plume dispersion. By coupling it with the Open GIS component Dotspatial, we have achieved geospatial visual representation of the calculation results, which has solved the problems of low calculation efficiency and insufficient ...

body the results of the coefficient data; e, the inner surface of the body carry out trigonometric formulas fitting coefficient; formula f, the reference specification hyperbolic cooling tower, made straight - equivalent wind load standard taper surface segment type cooling tower value calculation ...
Performance calculationBased on the analysis of air flow and heat transfer in the dry-cooling tower for Harmon system, a combined iteration method is presented to solve the coupled heat transfer and draft equations derived from theoretical and empirical formulas, with the size of the exchangers and...
The major considerations are mainly based on the water volume of the cooling tower, the flow rates of the water replenishment and discharge, and the minerals contained in the water; calculations are made according to physical relationships and to further derive the three related formulas, primarily...
2.1. Calculation Methods Heat recovery units have been used in air handlers for a long time for the pre-treatment of outdoor air. With the help of heat recovery units, the relative cooling energy of the exhaust air can be used to pre-cool the outdoor air. The efficiency of heat recovery...
However, a large number of empirical formulas were used in the mathematical model of heat transfer, and the calculation results of the model depended on the selection of empirical formulas. In 2010, Geng [42] pointed out that there were three main heat transfer mechanisms in the liquid film:...
2.4.5. Land Surface Albedo Calculation For Landsat TM/ETM data, Liang et al. [65] recommended using five bands, including blue (bBlue, 0.45–0.52 μm), red (bRed, 0.63–0.69 μm), near-infrared (bNIR, 0.77–0.90 μm), short wavelength infra-red 1 (bSWIR1, 1.55–1.75 μm), an...
