Modeling of Dry Out Incipience for Flow Boiling in a Circular Microchannel at a Uniform Heat Flux
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dryout is an essential phenomenon that has been observed experimentally in both slug and annular flow regimes for flow boiling in mini and microchannels. The dryout leads to a drastic drop in heat transfer coefficient, ...
Prediction of the Onset of Flow Instability in a Single Horizontal Microtube With an Inlet Orifice
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A methodology to predict the onset of flow instability (OFI) in a single horizontal microtube with an inlet orifice is developed based on the predication of pressure drop. The predictive methodology states, for the same ...
Experimental and Numerical Evaluation of a Scaled Up Micromixer With Groove Enhanced Division Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel passive enlarged micromixer has been proposed and experimentally and numerically investigated in this study over 0.5 ≤ Re ≤ 100. Flow visualization was applied to qualitatively assess flow patterns and ...
Effect of Inlet Restriction on Flow Boiling Heat Transfer in a Horizontal Microtube
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow boiling heat transfer in a horizontal microtube with inlet restriction (orifice) under uniform heating condition is experimentally investigated using FC72 as working fluid. A stainless steel microtube with an inner ...
Investigation of Bubble Frequency for Slug Flow Regime in a Uniformly Heated Horizontal Microchannel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Slug flow is an essential flow pattern observed in microchannels where its transition boundaries in microchannels are characterized by two complex hydrodynamic phenomena, the bubble confinement and the bubble coalescence. ...
