We describe the formation, characterization and theoretical understanding of microlenses comprised alternating polystyrene polymethylmethacrylate layers produced by multilayer coextrusion. These lenses are fabricated photolithography, using a grayscale mask followed plasma etching, so that refractive index alternation bilayer stack appears across radius microlens. The quarter-wave thick form one-dimensional photonic crystal whose dispersion augments material dispersion, allowing one to...
Air-to-refrigerant heat exchangers (HXs) are vital components of HVAC&R systems. Such HXs often use extended surfaces (fins) to overcome large airside thermal resistance despite fins’ intrinsic increased pressure drop, material cost, and fouling potential. However, advancements in Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA), optimization algorithms have led a paradigm shift eliminate fins through primary transfer surface optimization. In this work, automated CFD FEA...
