Heat Transfer Coefficients of Moving Particle Beds from Flow-Dependent Particle Bed Thermal Conductivity and Near-Wall Resistance
Sarath R. Adapa, Xintong Zhang, Tianshi Feng +5
Determination of heat transfer coefficients for flowing packed particle beds is essential to the design of particle heat exchangers, and other thermal processes. While such dense g…
Micromechanical Origin of Heat Transfer to Granular Flow
Xintong Zhang, Sarath Adapa, Tianshi Feng +5
Heat transfer to a granular flow is comprised of two resistances in series: near the wall and within the bulk particle bed, neither of which is well understood due to the lack of e…
