The Characteristics of Flow and Wall-to-bed Heat Transfer for Vertical Dense-phase Transport Flow
TLDR
In this article , the heat transfer capacity of dense-phase transport flow as a heat transfer fluid (HTF) in a vertical tube was demonstrated, and a semi-empirical correlation was developed relating the Nusselt number to Froude number, Reynolds number, and particle-tube diameter ratio.About:

Heat transfer fluids for concentrating solar power systems – A review
TL;DR: In this paper, the current status of heat transfer fluid, which is one of the critical components for storing and transferring thermal energy in concentrating solar power systems, is reviewed in detail, particularly regarding the melting temperature, thermal stability limit and corrosion issues.

Mechanism of heat transfer to fluidized beds
H. S. Mickley,D. F. Fairbanks +1 more
TL;DR: In this paper, the heat transfer coefficients obtained with fluidized beds are found to be proportional to the square root of the thermal conductivity of the quiescent beds, which indicates that the process controlling fluidized heat transfer may be considered to be an unsteady-state diffusion of heat into mobile elements of quiesent bed material.

Further studies of the regimes of fluidization
J. Yerushalmi,N.T. Cankurt +1 more
TL;DR: In this article, the authors present data obtained with several solids in cold model rigs, which serve to delineate the fluidization regimes noted above and their boundaries, and also throw light on the phenomenon of choking.

Flow regime diagrams for gas-solid fluidization and upward transport
H.T. Bi,John R. Grace +1 more
TL;DR: The boundary between fast fluidization and dilute-phase pneumatic transport is set by the type A choking velocity, at which the uniform suspension collapses and particles start to accumulate in the bottom region of the transport line as mentioned in this paper.

Time-series analysis of pressure fluctuations in gas–solid fluidized beds – A review
J. Ruud van Ommen,Srdjan Sasic,John van der Schaaf,Stefan Gheorghiu,Filip Johnsson,Marc-Olivier Coppens +5 more
TL;DR: It is concluded that progress has been made in understanding fluidized-bed dynamics by extracting the relevant information from pressure fluctuation data, but the picture is still incomplete.
