Fluid Flow and Rotating Equipment

Phenomenon of flow distribution in manifolds

Flow distribution is widely encountered in refinery operations, such as air distribution to burners, fluid distribution to parallel heat exchangers and the distribution of reactants in reactors.

Flow distribution is widely encountered in refinery operations, such as air distribution to burners, fluid distribution to parallel heat exchangers and the distribution of reactants in reactors. Uniform distribution is of paramount importance in all operations to achieve higher equipment efficiency and reliability. Although design considerations for fluid distribution devices are available, these may be overlooked by designers and lead to flow maldistribution. Many engineers have difficulty in conceptualizing the phenomenon of distribution through a manifold, depicted in FIG. 1, which is a header with a closed end and flow outlet points along its length.
