Parametric study of stresses in cooling-tower shells
… made in studying the structural behaviour of cooling tower shells, focusing more on the effect of wind on the structure and shape imperfections. However, little has been investigated on the most basic loading condition, i.e. self-weight load. This thesis focuses on a cooling tower with uniform …

General equation for predicting cooling tower approach temperatures at lower wetbulbs
Cooling tower approach temperature is the difference in leaving water temperature and entering air wet-bulb temperature. Cooling tower manufacturers describe the design capacity with water volumetric flow, entering water temperature, leaving water temperature, and entering air wet-bulb temperature. …

Performance tests and cooling effect distribution of the V.P.I. forced draft cooling tower
Test data of forced draft cooling towers is all too meager, and that available is, in many instances, incomplete. It is the opinion of the authors that putting cooling tower design on a rational basis can be brought about only by two methods. Either complete and intensive study of all existing …

Stability behaviour and dynamic response of cooling towers subjected to wind loading
… parametric analysis is presented for various cooling tower shell geometries. The shells are subjected to increasing wind pressures (speeds) to observe the trends in the critical buckling pressures/speeds at which the shell first buckles and the corresponding buckling modes. The cooling tower's …

Heat Transfer Enhancement using Iron Oxide Nanoparticles
… for heat transfer properties in industrial cooling systems. The nanofluids either had 30 nm particles with a wide size distribution to include particles greater than 1 micrometer or 15 nm particles with greater than 95% of the particles less than 33 nm. Calorimetry and thermal circuit …

Software for fault detection in HVAC systems in commercial buildings
… order faults such as simultaneous heating and cooling and imbalanced airflows within several large air-handling units were targeted. Savings of around $22,500 were predicted when the fault of simultaneous heating and cooling was occurring over the entire month in an air handler. Some of the …

Optimal Allocation of Building Cooling Loads to Chilled Water Plant Equipment
… a chiller plant consisting of liquid chillers, cooling towers and pumps. To meet the changing demand for cooling, most buildings have automated systems that control the operation of the chilled water plant. The system that controls the chilling equipment selects the temperatures of the water …

Role of the Curved Parametric Element in Linear Analysis of Thin Rotational Shells.
… perspex models in the shape of a cooling Tower were formed and tested in order to verify the existence of any correlation between theoretical and experimental results. These tests covered linear, small displacement response of the model for both static and dynamic …
