The crossflow heat transfer characteristics of a tube array subject to a dilute gas-solid suspension flow have been investigated. For a tube located in the first row of the array, the results indicate that an increase in the thermal capacity of the mixture is the dominant influence on heat transfer and a correlation for predicting the Nusselt number enhancement is developed. At the second row, the Nusselt number is influenced by thermal property changes and delayed boundary layer separation, whereas heat transfer in the third and later rows is determined by a combination of thermal capacity effects and changes in the flow structure and turbulence levels within the array.
