TP22-21: FEM Study Concept Study on the Anisotropic Mechanical Behavior of Cooling Tower Film Fills Deposit Control

TP22-21: FEM Study Concept Study on the Anisotropic Mechanical Behavior of Cooling Tower Film Fills Deposit ControlCooling tower fills made from foils are very anisotropic in their mechanical behaviour. That means, their deformation and load behaviour is not identical in all spatial directions. If you want to mechanically model fill blocks inside a cooling tower at an aggregated level, you have to take this anisotropic behaviour into account. The reasons for this are not so much due to the material itself but to the fill design. In this FEM concept study

if uncontrolled

CFD was used to show that the large fan design virtually eliminates hot air recirculation compared to 5% to 35% recirculation rates of traditional small fan designs

Recognizing and understanding this

allowing response time to be cut to 85%

design of the electrolysis cell

it is possible to prevent windmilling and provide secondary benefits that reduce installation and maintenance costs

Case histories are cited indicating the problems encountered

A review of wood structures

further testing should be conducted to verify an expand the results found in this study

VFDs can significantly reduce energy consumption and operating costs of the entire system while providing operational benefits to the owner
