RISIncompressible Criterion and Pressure Drop for Gaseous Slip Flow in Circular and Noncircular Microchannels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Slip flow in various noncircular microchannels has been further examined, and a simple model for a normalized Poiseuille number is proposed. As for slip flow, no solutions or graphical and ...
Erratum: “New Correlative Models for Fully Developed Turbulent Heat and Mass Transfer in Circular and Noncircular Ducts” [Journal of Heat Transfer, 2012, 134(1), 014503]
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the paper of Duan [1], there is an error in the range of the Prandtl number (Pr) for Eqs. (14) and (15). The correlations of Notter and Sleicher [2], Eqs. (14) and (15), are valid for ...
