Pig producers prefer to have automated control systems installed in their indoor environments because it reduces labor and enhances control precision. The effectiveness of two ventilation systems (forced and natural) were examined in several nursery

Because of the relatively high portion of dry matter accumulated within the leaves of the lettuce plant, the accuracy and sensitivity of a lettuce growth model may be improved by accurate and detailed morphological and physiological characteristics o

Estimates of the rate of heat loss from animals to the environment are used to determine food requirements of domestic species in relation to weather or their need for shelter, and to establish the extent to which climate influences the behavior and

This article reports on the computed flow characteristics of a slot-ventilated enclosure. The flow was mathematically modeled with an asymptotically consistent low-Reynolds-number {kappa}-{epsilon} model. A comparison of computed and experimental flo

As measures of air flow pattern similarity in Slotted-Inlet Ventilated Enclosures (SIVE), the inlet Reynolds number (Re) and the inlet jet momentum number (J) were found to be inappropriate. A criterion was derived from the ratio of inlet jet momentu

Results of simulations from a computer model developed to determine economically optimum day temperature for greenhouse hydroponic lettuce production are presented. Selected optimum air temperature is a function of many factors including available in

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

Skin temperature may act as a stimulus on animal performance during heat stress. A mechanistic model is developed to predict the skin surface temperature, temperature profile through the fur layer, and sensible and latent heat fluxes at the skin surf

This technical note presents an anomaly in the use of the Reynolds number as a kinematic similarity criterion for scale modeling of slot-ventilated enclosures and, based on theoretical considerations and experimental observations, proposes the Euler
