Pigs are subjected to intensive environment control and management for higher
productivity due to their sensitivity to climatic variation, which affects their growth. The
aim of the current work is to numerically model the air speed and temperature in
mechanical ventilation pig housing to achieve optimum environment control. The
simulation model was assumed as a steady two-dimensional numerical model including
the effect of buoyancy, turbulence and heat generated by the pigs. The model was solved
using the computational fluid dynamics software, Fluent, which is based on the integral
volume method. Air flow pattern and temperature inside the pig housing and at the pigs' level were predicted for different arrangements of inlet widths and inlet velocities in the
range of 1 - 5 ms-1. Different layouts were set up to determine the optimum design for the
thermal comfort zones under daylight situation with ambient temperature of 30c degrees and
night situation with ambient temperature of 26c degrees. From the analysis, location of inlets
and outlets has to be carefully considered in order to enhance the air distribution in the
pig housing. The use of water sprayer system during daylight was essential for pig
housing in Malaysia to provide thermal comfort for the pigs. CFD analysis helped to
identify problems in the design and offer suggestion for improvements. However, more
work must be done to further evaluate other arrangements, and to conduct three
dimensional simulations.
