Radial heat transport in packed beds at elevated pressures
Values were measured for the effective radial, heat conductivity d,, T and the heat transfer coetbcient at the wall CC, in a packed bed. This was done for superficial velocities of 5-70 cm SC’ and at pressures from l-10 bar. Values for i efr, r and rw were obtained by simultaneous fitting of measured axial and radial temperature profiles. The bed diameter was S cm; it was filled with 6.1 mm Ras...
متن کاملModelling radiative heat transfer in packed beds
A comprehensive approach for modelling dependent radiative heat transfer in beds of large (geometric range) spherical particles is presented. Such a system of large spheres lies in the dependent range even for large porosities. We show that the dependent properties for a bed of opaque spheres can be obtained from their independent properties by scaling the optical thickness while leaving the al...
متن کاملCFD Simulation of Porosity and Particle Diameter Influence on Wall-to-Bed Heat Transfer in Trickle Bed Reactors
Wall-to-bed (or wall-to-fluid) heat transfer issues in trickle bed reactors (TBR) has an important impact on operation and efficiency in this category of reactors. In this study, the hydrodynamic and thermal behavior of trickle bed reactors was simulated by means of computational fluid dynamics (CFD) technique. The multiphase behavior of trickle bed reactor was studied by the implementation of ...
متن کاملTransport of rodlike colloids through packed beds.
The effect of colloid shape on filtration rates in porous media was examined by constructing particles with different aspect ratios and measuring their retention in packed beds. Spherical polystyrene latex microspheres (1.0-microm diameter) were heated, stretched to the desired aspect ratio (2:1 and 3:1, with a 1:1 control), and quickly cooled. These particles were injected into minicolumns con...
متن کاملNumerical simulation of effect of non-spherical particle shape and bed size on hydrodynamics of packed beds
Fluid flow has a fundamental role in the performance of packed bed reactors. Some related issues, such as pressure drop, are strongly affected by porosity, so non-spherical particles are used in industry for enhancement or creation of the desired porosity. In this study, the effects of particle shape, size, and porosity of the bed on the hydrodynamics of packed beds are investigated with three ...
