RISComputational Modeling of the Mechanical Behavior of the Cerebrospinal Fluid System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational fluid dynamics (CFD) model of the cerebrospinal fluid system was constructed based on a simplified geometry of the brain ventricles and their connecting pathways. The flow is ...
Large Convective Heat Transfer Enhancement in Microchannels With a Train of Coflowing Immiscible or Colloidal Droplets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We show that heat transfer in microchannels can be considerably augmented by introducing droplets or slugs of an immiscible liquid into the main fluid flow. We numerically investigate the ...
Three-Dimensional Computational Modeling of Subject-Specific Cerebrospinal Fluid Flow in the Subarachnoid Space
Publisher: The American Society of Mechanical Engineers (ASME)
