Título del libro: Asme International Mechanical Engineering Congress And Exposition, Proceedings (imece) Título del capítulo: FLOW MALDISTRIBUTION IN MICROSYSTEMS: DESCRIPTION AND EFFECTS
Flow maldistribution is a fluid-management problem of interest in
engineering. It consists in the non-uniform distribution of various
flows in industrial applications like multiple accesses, manifolds,
bifurcations, spreaders, etc., where the fluid currents separate, detach
and reattach, break from the main body of the stream and splash within
the conducts, etc. Several effects in the operation of most systems and
apparatus where it occurs are common, including the interruption of
fluid currents, malfunctioning, and high energy consumptions. The
problem at industrial scale has been identified and treated mainly
through empirical considerations, but no totally solved. It has been
scarcely investigated however, in micro-technology applications with
unforeseeable situations in theses very small area/volume scales, with
appealing engineering tasks to solve. In any case, detailed analyses
must be conducted using fluid mechanics models with experimental
validation. In this paper the most relevant aspects of flow
maldistribution in micro-systems where intense heat and mass transfer
occur, are described. A review of their consequences and the current
trends for their remediation, are presented. Examples in MEMS, fuel
cells, micro-heat exchangers and micro-structured chemical reactors, are
considered.
