ABSTRACT: Ventilation systems used in swine facilities deserve to be studied because they directly affect productivity in the pig farming sector. Bearing this in mind the uniformity of air distribution and temperature is essential to animal welfare in this breeding environment. Thus, the purpose of this study was to identify whether changes in air entrances and exhaust fan positioning could influence air velocity and temperature distribution. The experimental data were collected in a commercial full-scale sow facility. Validation was carried out by comparing the simulated air temperatures and data measured in the field. These results showed agreement between data with a maximum relative error of approximately 3 %. The real settings showed a gradual... |

Fish morphormetric parameters namely; length, thickness, width at several points and weight were determined as a prelude and were used to design the furnace-dryer for investigating the effects of hardwood-charcoal particle size on five of its combustion properties under natural convection. The tests were in a dryer at zero load. One-factor experiment at five levels of the charcoal sizes of 10, 20, 28, 37 and 50 mm were used to study four of the properties namely, burn-out time (BOT), burning rate (BR), peak temperature (PT) and the time it takes for the temperature to peak (TTP). For the fifth property which is temperature gradient (TG), a 5×14, two-factor experiment was used. The above charcoal particle sizes form one factor while time after igniting... |
