“…Analytical integration of eq 10 to obtain eq 12 constitutes the use of a logarithmic mean driving force across each incremental volume. Inazumi and Kageyama (1975) present numerical computations to support the use of logarithmic mean enthalpy driving force for a cross-flow cooling tower of finite size. The structure of the numerical solution for Sa results in the implicit evaluation of x,+i ; for each incremental volume.…”

The flow rate and power requirement ratios decrease with increasing dimensionless frequency and ultimately approach values of unity. At low dimensionless frequencies, the flow and power ratios reach maximum asymptotic values.6. If the rheological behavior of a polymer solution or polymer melt can be described by an Ellis or power law model, the dimensionless graphs can be used to estimate flow rates and power requirements for a pulsating flow process.

“…Hayashi and Hirai [9] approximated the enthalpy of saturated air by a first-order equation with respect to water temperature, and applied the cross-flow heat exchanger calculations to obtain the overall enthalpy transfer coefficient with the aid of a chart. Inazumi and Kageyama [10] proposed a graphical method for the calculation of enthalpy driving force in a cross-flow cooling tower.…”

Cooling towers are widely used in most industrial units to reject waste heat to the environment. Wet towers are usually designed to operate in hot and dry weather conditions, but wet cooling towers operating in Ahvaz climate suffer from mixed weather conditions that strongly affect the thermal performance of the towers. Operating in mixed weather conditions and fouling on fills are two major concerns for towers working in the direct reduction unit of Khuzestan Steel Company (KSC), Ahvaz. The first step is to model the thermal behaviour of the tower under the present operating conditions. Two mathematical models (the conventional Merkel model and the dimensionless Halasz model) are applied in this step and the results of the models for the outlet water temperature in nine various operating conditions are compared with experimental data. Prevailing fill characteristic curves for three cell halves of the tower are obtained using a numerical-experimental method. At the second step, the results of the chemical analysis of fouling material and circulating water are considered to obtain the main factor of scale forming in the tower. The tendency of water to scale forming is investigated using three conventional scaling criteria. The analysis of water and fouling material shows that both air and water have important fouling and scaling effects on fills. Finally, several approaches are proposed to reduce these deteriorating effects of air and water. The effect of placing an impact separator in front of air louvers (to reduce suspended solids of the air) on the thermal performance of the tower is investigated.
