This book presents the topology optimization theory for laminar flows with low and moderate
Reynolds numbers based on the density method and level-set method respectively. The
density-method-based theory offers efficient convergence while the level-set-method-based
theory can provide anaccurate mathematical expression of the structural boundary.Unsteady
body-force-driven and two-phase properties are basic characteristics of the laminar flows. The
book discusses these properties which are typical of microfluidics and one of the research
hotspots in the area of Micro-Electro-Mechanical Systems (MEMS) providing an efficient inverse
design approach for microfluidic structures. To demonstrate the applications of this topology
optimization theory in the context of microfluidics it also investigates inverse design for
the micromixer microvalve and micropump which are key elements in lab-on-chip devices.
