Measurement of Thermal Conductivity along the Radial Direction in a Vertical Cylindrical Packed Bed

Heat transfer in packed beds and their thermal response have been of great interest for scientists and engineers for the last several years, since they play a crucial role in determining design and operation of reactors. Heat transfer of a packed bed is characterised through lumped parameter, namely, effective thermal conductivity. In the present studies, experiments were performed to investigate the thermal conductivity of a packed bed in radial direction. The packed bed was formed using iron ore particles. To determine the effective thermal conductivity a new transient methodology is proposed. The results obtained were compared with the models proposed by ZBS and Kunii and Smith

Erratum to: Estimation of Sintering Kinetics of Magnetite Pellet Using Optical Dilatometer

Authors have used a new way for measuring bulk volume based on the image (pixel) analysis named as Light Table Imaging (LTI), and subsequently bulk densities and porosities. Authors lately found that there was a slight error in calibrating the scale (known distance) to pixel measurement and understand the need to communicate the error and subsequent corrections.  Erratum in: Metallurgical and Materials Transactions B, vol. 47, iss. 1, p. 309–319, DOI: 10.1007/s11663-015-0505-9</p
