The effect of MHD flow on hydrothermal characteristics of ferro-nano-fluid in circular pipe

Edip Taskesen et al.

Summary: This study experimentally investigated the effect of a constant magnetic field on the convective heat transfer characteristics of Fe3O4/H2O ferro-nano-fluid with different volumetric concentrations flowing in a circular pipe. The results showed that increasing flow rate and applying a constant magnetic field enhanced the convective heat transfer.

Estimation of effective thermal conductivity and heat transfer coefficient of lithium orthosilicate pebble bed in carbon dioxide-air medium

N. S. Ghuge et al.

Summary: The effective thermal conductivity and heat transfer coefficients of lithium orthosilicate pebble bed in a CO2-air medium were investigated. The results showed that the effective thermal conductivity ranged from 0.2 to 0.75 Wm(-1)K(-1), and the heat transfer coefficients ranged from 14 to 63 Wm(-2)K(-1).

Experimental validation of a particle-based method for heat transfer incorporating interstitial gas conduction in dense granular flow using a rotary drum

Andrew M. Hobbs et al.

Summary: Conductive heat transfer in granular materials plays a crucial role in many industrial processes. A particle-based model, which incorporates the effect of interstitial gases, was validated through an experiment. The model demonstrates good agreement with experimental data, indicating its effectiveness in capturing the gas contribution in dynamic systems.

Numerical study on gravity-driven granular flow around tube out-wall: Effect of tube inclination on the heat transfer

Zhigang Guo et al.

Summary: This study investigated the effect of tube inclination on heat transfer in granular flow moving bed heat exchangers using a discrete element method. It was found that tube inclination can improve heat transfer by increasing the heat transfer area, but uncertainties exist in the local heat transfer coefficients. Additionally, different effects were observed at different locations along the tube, with bottom area benefiting from increased heat transfer coefficient and top or middle areas experiencing opposing effects.
