Misting systems for poultry housing have traditionally been characterized using evaporative cooling efficiency. This works well for evaporative pad systems, but poorly for misting systems since they are strongly affected by water pressure and ventila

A modification of the TEACH-T program (based on the k-£ model of turbulence transport) was applied to the problem of predicting air mixing patterns and velocities in a rectangular, slot-ventilated enclosure having a rectangular obstacle to flow. Com

First paragraph: Culturing fish requires that the animals be confined in some controllable volume such as a pond, raceway, net pen, or tank. An important goal with the culturing system is to provide the fish a satisfactory culture environment so that

A new method for implementing evaporative misting of broiler houses was developed and investigated. The method consisted of a nonlinear optimization of an objective function for bird comfort, subject to a set of constraints defining a thermal balance

The growth performance of tom turkeys maintained in closed and open confinement housing was examined. Treatments were initiated on the day of hatching and consisted of constant light intensity of 1, 11, 110, or 220 lx in an enclosed house or sunlight

A system design for evaporative cooling is presented that employs a continuous slotted inlet surrounded by an air inlet plenum that also supports the evaporative pad. Environmental performance data was collected over two summers in a renovated broile

A similitude approach was used to develop predictive graphs for the ventilation rate due to the stack or chimney effect. Using a half scale model of an open side wall structure with a continuous and unrestricted open ridge, it was found that (a) vent

THE design concept of a double solar attic is presented. This concept uses a single polyethylene surface placed within the attic space to provide greater convective heat transfer resistance. Analytical and experimental results demonstrate that this c

Amodel for predicting layer performance as a function of inside temperature was used to determine the effects of evaporative cooling and local climatic effects on economic return. A stochastic weather model analysis was used to determine the effects
